Abstract
When the screen-printed ZnS:Mn2+ nano-phosphor film is heated under ambient condition, the photoluminescence (PL)
intensity due to the d–d transition of Mn2+ decreases with increasing temperatures. The coating of 3-mercaptopropyl
trimethoxysilane (MPS) and SiO2 around ZnS:Mn2+ nanoparticles is effective to suppress the decrease in the PL intensity
by heating. This is explained by suppressing the oxidation of ZnS:Mn2+ nanoparticles and the carbonization of propyl chain in
MPS by SiO2 coating.
