| Abstract: | Abstract The glasses doped with ZnS:Mn2+ nanocrystals were successfully fabricated to study the size effects on the luminescent properties of ZnS:Mn2+.Photoluminescence measurements show the characteristic Mn2+ emission from within the ZnS host crystaland photoluminescent excitation measurements show a large blue shift of the excitation peak which is indicative of the increased band gap. An increased intensity of the SA emission was observed with the decrease in the size of the ZnS:Mn2+ crystallites. |
