Embodiment 1

[0067] A liquid metal quantum material, comprising a liquid metal layer and quantum dot particles; the liquid metal is a gallium indium alloy Ga 24.5 In, the quantum dot particles are CdS quantum dots,

[0068] The mass ratio of the liquid metal and the CdS quantum dots is 10:1.

[0069] The liquid metal quantum material thus prepared has the dual properties of liquid metal and CdS quantum dots, namely, electronic interconnection and quantum properties.

Embodiment 2

[0071] In this embodiment, the liquid metal quantum material described in Embodiment 1 is prepared by the following steps:

[0072] 1) Take the liquid metal gallium indium alloy Ga according to the proportion 24.5 In;

[0073] 2) The liquid metal is placed in an air environment for constant temperature treatment, the treatment temperature is 50°C, and the treatment time is 1 h; then stirring is performed, the stirring speed is 500 rpm, and the stirring time is 5 h; the liquid metal in a liquid state is obtained;

[0074] 3) The liquid metal is processed into a liquid state, placed in a solution of sodium dodecyl sulfate with a concentration of 1.5 mol / L, and the liquid metal is self-dispersed into micron-scale metal droplets by a mechanical injection method, and then The micron-scale metal droplets are broken up into nano-scale metal droplets with a diameter of about 50nm by high-intensity ultrasonic crushing and assisted by an external field;

[0075] 4) Add the CdS quantum...

Abstract

The invention relates to a liquid metal quantum material and a preparation method thereof. The liquid metal quantum material comprises internal quantum dot particles or quantum devices and liquid metals coated outside the quantum dot particles or quantum devices; or the liquid metal quantum material comprises internal liquid metal nano liquid drops and liquid metal compound layers coated outside the liquid metal nano liquid drops. The invention also discloses the method for preparing the liquid metal quantum material. The liquid metal quantum material provided by the invention has the unique properties of liquid state, flexibility and deformability; and the preparation difficulty of the material is greatly reduced, so that the electronic interconnection difficulty of traditional quantum materials or devices is greatly lowered, thereby being more beneficial to application of quantum technology.

Description

technical field [0001] The invention belongs to the field of quantum materials, in particular to a liquid metal quantum material and a preparation method thereof. Background technique [0002] Quantum materials are a large class of new materials that differ not only from microscopic atoms and molecules, but also from macroscopic objects in terms of physical, chemical and biological properties. Due to its inherent unique quantum confinement effect (also called quantum size effect), the material behavior of quantum materials is between macroscopic and microscopic objects, and often exhibits many novel new properties and effects. For example, when semiconductor crystals are as small as nanoscale (1 nanometer is about one ten thousandth of the width of a human hair), the same substance of different sizes can emit light of different colors, and the corresponding effect can be used for high-resolution fluorescence detection of tiny biological objects; More effects can also be use...
