Erbium doped 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.
