Description

Technical Field

[0001] The invention relates to an intelligent mechanical response luminescent heterojunction material and a preparation method and application thereof, belonging to the technical field of inorganic luminescent materials. Background Art

[0002] When mechanical luminescent materials are subjected to mechanical stress (such as compression, bending or friction), they can convert mechanical energy into light energy for release. This phenomenon is called piezoelectric luminescence effect or mechanical luminescence effect. A heterojunction refers to an interface region composed of two or more different semiconductor materials. These materials have different energy band structures and will form special electronic properties at the interface. When the heterojunction is subjected to external force, the piezoelectric material will produce charge separation and form an internal electric field. The presence of a heterojunction can enhance the charge separation effect of the mechanical luminescent material and improve the luminescence efficiency. Currently, the widely used mechanical luminescent materials are homogeneous, such as oxides, sulfides and perovskite structures. However, the homogeneous structure has low luminescence efficiency, slow response time and poor repetition stability. Summary of the invention

[0003] The present invention provides an intelligent mechanical response luminescent heterojunction material and a preparation method and application thereof to solve the above problems.

[0004] The purpose of the present invention is to provide an intelligent mechanical response luminescent heterojunction material, the chemical expression of which is xZnS-(1-x)CaZnSO: 1%Mn 2+ , where 0≤x≤1.

[0005] Another object of the present invention is to provide a method for preparing an intelligent mechanical response luminescent heterojunction material, comprising the following steps:

[0006] Step (a), prepare mixed powder

[0007] Mix ZnS, CaCO3 and MnCO3, ZnS and CaCO3 are mixed in a molar ratio of 1:0 to 1:1, and then 1% of MnCO3 by weight of the mixed powder is added; then ethanol is added for grinding, and mixed evenly to obtain a mixed powder;

[0008] Step (ii): assembling the reactor

[0009] (1) Put the mixed powder into a raw material reaction bottle and then place it in a reactor, and the outer layer of the reactor is coated with copper oxide powder; the mass ratio of copper oxide powder to mixed powder is 40:1 to 45:1, and the copper oxide powder can cover 2 / 3 of the height of the raw material reaction bottle;

[0010] (2) Prepare an insulation brick group, the insulation brick includes an insulation brick cover, an insulation brick body and an insulation brick bottom arranged from top to bottom, the insulation brick cover, the insulation brick body and the insulation brick bottom are arranged to form a cavity, and the insulation brick group is covered with insulation cotton from top to bottom; place the reactor at the center of the heat-resistant brick bottom, then place the heat-resistant brick body on the outside of the reactor, and then place the heat-resistant brick cover to cover the top of the heat-resistant brick body, and cover the insulation brick group with insulation cotton from top to bottom to obtain a reaction device equipped with mixed powder;

[0011] Step (iii), synthesis reaction

[0012] A microwave reactor is prepared, wherein a rotating disk that can be controlled to rotate is provided in the microwave reactor, wherein the rotating disk in the microwave reactor is controlled by an external control source and connected to an independent power supply, and a disguised rotation of the rotating disk is realized by switching between different gears;

[0013] The reaction device equipped with the mixed powder is placed in a microwave reaction furnace, on the circumference at 2 / 3 of the radius of the turntable, and reacted for 20 to 26 minutes at a microwave power of 1000 W. The turntable rotated counterclockwise and clockwise for 10 to 13 minutes respectively. After the reaction is completed, it is naturally cooled, and the sample is taken out and ground to obtain the intelligent mechanical response luminescent heterojunction material.

[0014] As a further preference of the above scheme:

[0015] In the step (i), 2 to 4 ml of ethanol is added to every 1 g of the mixture of ZnS, CaCO3 and MnCO3; after adding ethanol, the raw materials are ground to 200 to 260 meshes to obtain the mixed powder.

[0016] As a further preference of the above scheme:

[0017] The purity of the copper oxide powder in the step (ii) is 98%.

[0018] Another object of the present invention is to provide an application of an intelligent mechanical response luminescent heterojunction material, and the intelligent mechanical response luminescent heterojunction material is applied to a mechanical force responsive film. The preparation method is: the intelligent mechanical response luminescent heterojunction material is evenly mixed with PDMS colloid to obtain a mixed colloidal liquid, and then the mixed colloidal liquid is placed in a mold, and heated at a temperature of 60 to 70°C for 4 to 5 hours to obtain a transparent film with intelligent mechanical force response luminescence.

[0019] As a further preference of the above scheme:

[0020] The mass ratio of the intelligent mechanical response luminescent heterojunction material to the PDMS colloid is 1:8 to 1:10.

[0021] The beneficial effects of the present invention are as follows: the mechanical luminescence heterojunction material synthesized with microwave assistance has obvious mechanical luminescence phenomenon, high luminescence efficiency, high luminescence intensity, and does not require pre-charging of ultraviolet light or other rays, and can directly generate mechanical luminescence phenomenon by applying external force; the synthesis process is simple to operate, the environment is mild, no toxic reagents are required, and no harmful gases are generated, which conforms to the concept of green environmental protection, as follows: (1) The intelligent mechanical response luminescence heterojunction material prepared by the method of the present invention has higher luminescence efficiency and high-intensity light visible to the naked eye; faster response speed, only 0.1 or even shorter time from applying mechanical force to luminescence; lower power consumption, no need for pre-excitation in advance; better mechanical properties and better charge control, showing higher application potential in stress sensing, tactile feedback and optical display, anti-counterfeiting encryption, monitoring and early warning and other fields; (2) The traditional high-temperature solid phase method is to heat the sample by thermal radiation, which has high time cost and low energy utilization rate. Special samples need to pass reducing gas or protective gas, which wastes resources. The traditional hydrothermal method requires toxic organic reagents, the reaction waste pollutes the environment, and the operation method is cumbersome. The microwave method of the present invention shortens the process time (only 20 to 25 minutes are needed for synthesis) and reduces the time cost; the microwave ultra-high temperature assisted heating method used in the present invention directly heats the material using microwave energy, and the mechanical luminescent heterojunction material is prepared by the microwave ultra-high temperature assisted method, which not only shortens the process time, reduces the time cost, but also improves the product stability; (3) The ultra-high temperature microwave assisted method of the present invention uses copper oxide powder as a microwave absorption medium, and no reducing atmosphere is generated, so that the material reacts in a stable atmosphere, so that the material can react stably. Copper oxide powder as a medium can enable the microwave method to synthesize samples that are easily reduced and unstable, and activated carbon powder as a medium can synthesize samples under reducing atmosphere conditions. The use of the two methods provides the same atmosphere conditions as the traditional solid phase method for synthesizing various samples; in addition, the use of copper oxide powder can make the core temperature reach above 1000°C in a short time; the copper oxide powder must be placed tightly and flatly to prevent the copper oxide powder from flying and causing damage to the product performance; (4) The turntable built into the existing microwave reactor can only rotate in one direction when in use, and the material can only rotate in one direction to receive microwave energy, resulting in uneven reaction of the material; the turntable built into the microwave oven in the method of the present invention changes the rotation direction at regular intervals when in use, so that the material can rotate in two directions to receive microwave energy more evenly. Specifically: the turntable of the reaction device adopts bidirectional rotation. After rotating in the forward direction for a set time, it rotates in the reverse direction for the same set time. The bidirectional rotation can make the material fully and evenly receive microwave radiation, and receive different bands in all directions, so that the material can react more evenly and fully; (5) The reaction device of the present invention is placed on a circumference deviating from the center of the reaction device, so that the reaction device can evenly receive the microwaves emitted by the transmitter. It is difficult to determine whether the center of the reaction device is the peak or trough of the microwave. Placing the heat-resistant brick group at a position off-center can receive different bands, so that the mixed powder can react evenly. BRIEF DESCRIPTION OF THE DRAWINGS
