摘要： 采用微波法和溶胶-凝胶法制备了(Y2O3:Er3+)粒子. 微波法制备过程中烧结温度降低到600 ℃. 980 nm激光激发下得到550 和660 nm两个上转换发射带. 微波法制备的上转换材料得到了强的红光发射和弱的绿光发射, 溶胶-凝胶法制备的材料得到了强的绿色发射和弱的红光发射. 结果表明, 微波促进了S6对称性的形成, S6对称性促进了红光的发射.

Abstract: Erbiumdoped Y2O3 (Y2O3:Er3+) particles were prepared by microwave method and sol-gel method. Using microwave method the calcining temperature was decreased to 600 ℃. Two upconverting emission bands centered at 550 and 660 nm were presented under 980 nm laser excitation. Samples prepared by microwave method showed a strong red emission and a week green emission, while samples prepared by sol-gel method showed a strong green emission and a week red emission. The results showed that microwave promoted the formation of S6 symmetric structures and the S6 symmetric structures promoted the red emission.
