When the screen-printed ZnS:Mn 2+ nano-phosphor film is heated under ambient condition, the photoluminescence (PL) intensity due to the d-d transition of Mn 2+ decreases with increasing temperatures. The coating of 3-mercaptopropyl trimethoxysilane (MPS) and SiO 2 around ZnS:Mn 2+ nanoparticles is effective to suppress the decrease in the PL intensity by heating. This is explained by suppressing the oxidation of ZnS:Mn 2+ nanoparticles and the carbonization of propyl chain in MPS by SiO 2 coating.
