在水相中制备了高质量的 CdTe 纳米晶, 并制备了适合微加工的 CdTe 纳米晶-聚合物复合物, 将此复合物溶液分散到快速搅拌的聚乙烯醇(PVA)水溶液中, 除去溶剂, 得到了高荧光强度的微米级复合微球. 利用共聚焦荧光显微镜研究了分散过程中复合物溶液浓度, PVA 浓度及搅拌速度等对微球尺度及形状的影响, 通过调节这些实验条件实现了对复合微球的控制.
High quality CdTe nanocrystals were prepared in the aqueous phase and a CdTe nanocrystal-polymer composite suitable for microfabrication was prepared. The composite solution was dispersed in a rapidly stirred aqueous solution of polyvinyl alcohol (PVA) and the solvent was removed , The micrometer-scale composite microspheres with high fluorescence intensity were obtained.The influences of the concentration of the composite solution, the concentration of PVA and the stirring speed on the microsphere size and shape during the dispersion process were studied by using a confocal fluorescence microscope. By adjusting these experimental conditions, Control of composite microspheres.
