中文摘要：

从使用一个反向的 micelle 方法做的 CdS nanocrystals 的有效蓝色，绿色，橘子和红光的观察被报导。蓝光大约 480 nm 被归因于电子洞对的放射的再结合。在 650 nm 附近的红光由于处于 nanocrystal 表面缺点状态套住的激子的放射的再结合。乐队边排放和表面陷井状态排放的不同部分的联合为 nanocrystals 导致绿色和橘子光。有有效的多种色彩的光的 CdS nanocrystals 可以在完整的颜色显示和 biolabelings 发现潜在的申请。

英文摘要：

The observation of efficient blue, green, orange and red luminescence from CdS nanocrystals made by using a reverse micelle method was reported. The blue luminescence about 480 nm is attributed to the radiative recombination of electron-hole pairs. The red luminescence around 650 nm is due to the radiative recombination of the exciton trapped in the nanocrystal surface defect states. The combination of different portion of band-edge emission and surface trap state emission results in green and orange luminescence for the nanocrystals. The CdS nanocrystals with efficient multicolored luminescence may find potential application in full color displays and biolabelings.
