Abstract
A method for preparing a fluorescent semiconductor nanocrystal material. At least one semiconductor nanocrystal precursor is uniformly mixed with a micro/mesoporous material to form a mixture. The mixture is calcined under a temperature higher than or equal to a collapse temperature of the micro/mesoporous material to obtain the fluorescent semiconductor nanocrystal material. This application also provides a fluorescent semiconductor nanocrystal material prepared through the method, and applications thereof in the manufacture of a light-emitting diode device and a color conversion display panel.
Claims18
A method for preparing a fluorescent semiconductor nanocrystal material, comprising:
- (1) uniformly mixing at least one semiconductor nanocrystal precursor with a micro/mesoporous material to form a mixture;
- and
- (2) calcining the mixture under a temperature higher than or equal to a collapse temperature of the micro/mesoporous material to make pores of the micro/mesoporous material collapse, encapsulating the at least one semiconductor nanocrystal precursor in the pores of the micro/mesoporous material to produce the fluorescent semiconductor nanocrystal material;
- wherein the at least one fluorescent semiconductor nanocrystal material is in a form of powder.
