英文摘要: Bi3+ and Er3+ codoped Y2O3 was prepared by sol-gel method. The upconversion emission was investigated under 980 nm excitation. For samples without Bi3+, the quenching concentration of H-2(11/2)/S-4(3/2) level of Er3+ is 3.0 mol%. However, by 1.5 mol% Bi3+ doping the quenching concentration increases to 5.0 mol%; meanwhile, the green emission is enhanced 1.9 times. The results indicate that both the quenching concentration and the emission intensity of H-2(11/2)/S-4(3/2) level can be increased by Bi3+ doping. (C) 2011 Elsevier B.V. All rights reserved.
