摘要：The aim of this study is to prepare nanoparticles molybdates doped with rare earth ion Eu³⁺ synthesized by sol-gel method to study the luminescence property of these crystal powders. The influence of pH and doping amount of Eu³⁺ on these nanoparticles was also investigated. The results showed that CaMoO₄: Eu³⁺ (6%, mass ratio) prepared in pH value 7-9 and calcined at 700°C became uniformly cubic crystal and exhibited red photoluminescence with strongest emission peak at 612×258 nm excitation, which was caused by ⁵D₀→⁷F₂ transition of Eu³⁺. It can be predicted this CaMoO₄: Eu³⁺ phosphor could be a potential phosphor material for white-light LED application in the future.
