▎ 摘　　要

NOVELTY - Preparing a highly thermally stable fluorescent light concentrator comprises (1) coating a boride or sulfur-based metal compound shell on the surface of the quantum dot to obtain a heterostructure quantum dot with a shell structure; and (2) uniformly mixing the heterostructure quantum dots with a shell structure, graphene and polymer solution. USE - The method is useful for preparing the high-heat stable fluorescent light collector. ADVANTAGE - The method covers the shell layer structure on the outer surface of the quantum dot, which can effectively isolate the quantum dot from the outside; the quantum dot will not be directly graphene contact with the heat conducting material, avoids the fluorescence quenching of electron transfer trigger at the same time graphene the material has high heat conductivity absorption, effectively reducing the heat generated by the fluorescent condenser when working, so that the fluorescent condenser has thermal stability, and keeping high photoelectric conversion rate.
