To understand the photoluminescence (PL) mechanisms of nanophosphors, various experiments were conducted. The SnO2:Eu3+ nanoparticles were synthesized and calcined at various temperatures. The increase of the PL intensities with the increasing calcination temperature was due to the removal of the hydroxyl groups, and to the decrease of the surface area caused by the growth of the nanoparticles. Additionally, Mn-doped zinc sulfide monodispersed-nanoparticles were synthesized. The influence of Mn doping concentration was investigated with the decrease of crystallinity and capping. The increased crystallinity and removal of water/organic capping were suggested for the reasons of increased PL property.
