Abstract

ZnS:Mn

nanocrystals were dispersed within a PVB polymer matrix to study the effects of size and quantum confinement on the luminescent properties of ZnS:Mn. An increased intensity of the SA emission was observed with the decrease in the size of the ZnS:Mn

nanocrystallites. And the emission measurements show a large blue shift of the SA emission peak. RILE effect is also observed and it is stronger than that in ZnS:Mn

colloids. It implies that the surface states are more stable in PVB films.
