1. 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.
