Abstract

ZnCdS/SiO₂ nanocrystals with core-shell structure were fabricated by Micro-emulsions method via the hydrolysis of tetraethyl orthosilicate (TEOS). Using XRD and TEM, the size of capped nanocrystals was around 22nm with the uncaped round 12nm. Emitting peaks in PL spectra of ZnCdS shifted from 390nm to 540nm by adjusting the proportion of Zn/Cd. The water solubility and optical property are both obviously enhanced after the capsulation of SiO₂.
