XAFS Study on Ag2S Semiconductor Clusters Designed in Nanopores and Their Photoluminescence Properties

Abstract

Ag 2 S clusters were prepared in microporous ZSM-5 and mesoporous AlMCM-41. The state of Ag was analyzed by EXAFS. The pore size of the host has great effects on the photoluminescence property of Ag 2 S. Compared with Ag 2 S/ ZSM-5, the emission of Ag 2 S/ AlMCM-41 shifts to the longer wavelength region.
