| Abstract: | Y2O3:Eu3+ red phosphor was synthesized by roasting assisted with(NaCl+S+Na2CO3) compound molten salt using Y2(C2O4)3:Eu3+ as precursor.The effects of components and amount of compound molten salt,sintering temperature and time on the particle size,morphology and luminescent properties of Y2O3:Eu3+ phosphor were mainly studied by XRD,SEM and luminescence spectrum.The results indicate that the suitable mol fraction content of NaCl is between 40%~45%(based on the total mol of compound molten salt),the optimal ... |
| Keywords: | Y2O3:Eu3 phosphor compound molten salt method particle size luminescent intensity |
