preparation example Construction

[0042] The present invention also provides a method for preparing a force-luminescence composite material according to an embodiment, which includes the following steps: mixing and sintering eggshells, zinc sulfide and a compound containing doped ions to prepare a force-luminescence composite material. Including mZnS-nCaZnOS: xM, where M is a doped ion, and m, n and x represent the number of moles of ZnS, CaZnOS and M, respectively.

[0043] Specifically, the egg shell is selected from at least one of egg shells, duck egg shells, goose egg shells and bird egg shells. The main component of the eggshell is calcium carbonate, with a mass percentage of up to 95%, and the remaining components are protein (about 3.5% by mass) and a variety of trace elements (zinc, copper, manganese, etc.), which are very suitable as a calcium source It is used for the low-cost production and related applications of zinc sulfide-zinc oxyzinc calcium calcium luminescence composite materials.

Embodiment 1～ Embodiment 6

[0070] The preparation process of the photoluminescent composite material of Example 1 to Example 6 is as follows:

[0071] (1) Weigh the raw materials according to the raw material ratio in Table 1 and mix them in an agate mortar, then add an appropriate amount of absolute ethanol, grind until the ethanol is almost volatilized, and then repeat the above grinding process.

[0072] (2) Transfer the ground powder to an alumina ceramic boat, and place it in a blast drying oven at 70°C for 5 hours in the atmosphere, and then transfer it to a high temperature tube furnace at a temperature of 5°C / min The speed was increased to 1100°C, and the temperature was kept for 6 hours in an Ar atmosphere. After the alumina ceramic boat is cooled to room temperature with the furnace, the sample is taken out, crushed, and sieved to obtain the zinc sulfide-zinc oxyzinc calcium calcium luminescence composite material of the embodiment.

Abstract

The invention relates to a mechanoluminescence composite material as well as a preparation method and application thereof. Raw materials for preparing the mechanoluminescence composite material comprise eggshells, zinc sulfide and a compound containing doping ions, wherein the mechanoluminescence composite material comprises mZnS-nCaZnOS:xM, M is the doping ions, and m, n and x respectively represent mole numbers of ZnS, CaZnOS and M. Compared with a mechanoluminescence composite material prepared by taking high-purity calcium carbonate as a calcium source, the mechanoluminescence composite material prepared by taking eggshells as the calcium source and combining zinc sulfide and doped ions is low in cost and wide in raw material source. In addition, experiments prove that other componentsin the eggshell do not influence the luminescence property of the mechanoluminescence composite material. Therefore, the mechanoluminescence composite material is low in cost, good in luminescence property and beneficial to large-scale production and application.

Description

Technical field [0001] The invention relates to the field of luminescent materials, in particular to a luminescence composite material and its preparation method and application. Background technique [0002] Lizhi luminescent material is a luminescent material that directly converts mechanical stimulation into light without external electric field or light source. It has shown great application prospects in the fields of new light source and display, biological imaging, building flaw detection and health monitoring, pressure sensing, etc. . According to incomplete statistics, half of the inorganic solids and about one third of the organic solids have powerful luminescence properties. Although there are many kinds of Lizhi luminescent materials, the ones currently found have high brightness (>100cd / m 2 ), self-recoverable luminescence materials are also limited to rare earth ion doped strontium aluminate, transition metal ion doped zinc sulfide and transition / rare earth ion d...
