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.
Key words: Luminescence property, molybdate, phosphor, sol-gel method, , ,
