摘要：
Highly fluorescent CdTe nanocrystals were synthesized in aqueous solution, and then processible CdTe nanocrystal-polymer composites were fabricated by coating the aqueous nanocrystals with copolymers of styrene and octadecyl-p-vinyl-benzyldimethylammonium chloride (SOV- DAC) directly. A dichloromethane solution of CdTe nano- crystal-polymer composites was dispersed in the aqueous solution of poly (vinyl alcohol) (PVA) generating highly fluo- rescent microspheres. Experimental parameters such as the concentration of nanocrystal-polymer composites, the con- centration of PVA, and stirring speed which had important effect on the preparation of the microspheres were investi- gated in detail with fluorescent microscope characterization.
