摘要：
Y2O3:Yb3+ nanocrystals codoping with Li+ ions were synthesized by glycine combustion method. Codoping with Li+ ions leads to about 12 times enhancement of the photoluminescence (PL) intensity around 1 mu m in terms of the increased lifetimes at 1026 nm from 0.384 ms to 1.42 ms at room temperature. The enhancement in the PL intensity could be mostly attributed to the modification of the local symmetry around Yb3+ ions by codoping with Li+ ions. (C) 2010 Elsevier B.V. All rights reserved.
