The effects of temperatures of vacuum evaporation and calcination on the luminescent properties of the commercial rare earth phosphor Y2O3:Eu3+ were investigated.

Moreover,it gives the outlook of rare earth phosphor used for lamp.

Experiment study on RE polishing powder grinding;

The raw materials of high function polishing powder come from rare earth carbonateThe technological conditions of preparing polishing powder from rare earth carbonate such as roasting and screening were studiedAccording to polishing rule,the effect factors of polishing was analysedSo the best technological conditions are found and high function polishing powder is produced
