Yb3+,Er3+共掺BaGd2ZnO5材料的制备及其上转换发光效率
Preparation and Up-conversion Efficiencies of Yb3+, Er3+ Co-doped BaGd2ZnO5
摘要
Abstract
BaGd2Zn05 phosphors with different doping concentrations of Yb3+, Er3+ were prepared by using the sol-gel method. Up-conversion fluorescence powers and efficiencies were measured under different excitation density. The obtained data show that each sample has a maximum value in emission power. Among those sample, the sample of doping Yb3+ (4% ), Er3+ (1% ) has the highest power of 20 mW. Each sample had a maximum value of up-conversion absolute fluorescence efficiency. This value shifts to the lower exciting density with the increasing content of Yb3+ and Er3+. The highest efficiency is 3. 2% for Yb3+ (9%) and Er3+ (3%) sample, and the highest fluorescence efficiency is 6.9%.关键词
