Photoluminescence properties of Ag2S semiconductor clusters synthesized in micropores and mesopores

Photoluminescence properties of Ag2S semiconductor clusters synthesized in micropores and mesopores Silver sulfide (Ag2S) clusters were synthesized in microporous zeolites and mesoporous AlMCM-41 by the sulfurization of Ag+ ions exchanged within the pores of the host. Characterization was performed by means of XRD, UV-Vis Ag K-edge XAFS and photoluminescence. The pore size of the host has great effects on the photoluminescence properties. Ag2S/AlMCM-41 showed photoluminescence at the longer wavelengths than Ag2S/zeolites. The photoluminescence band of Ag2S in the zeolite with 1-dimensional channels was narrow in comparison to the Ag2S in zeolites with 2- or 3-dimensional channels. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
