Surface passivation of CdS/Zn2SiO4 nanocomposites prepared by a wet chemical route

Abstract:
Highly luminescent CdS/Zn2SiO4 nanocrystals were prepared by a wet chemical method. The effect of surface passivation was observed in photoluminescence measurements of CdS nanocrystals embedded in colloidal nanocrystallite or amorphous Zn2SiO4 matrix. The resultant luminescent emission of as-prepared CdS/Zn2SiO4 nanocomposite thin films displays two distinct components. One is attributed to the band-edge emission and the other is due to the surface defects. The effect of aging on CdS/Zn2SiO4 nanocomposite thin films has been investigated, showing the active role of Zn2SiO4 matrix in modifying the surface states.
