摘要：
The optical properties of Gd2O3: Er (0.25-8 mol%) nanoparticles have been investigated. The observed effect of energy transfer from lattice Gd3+ to activator Er3+ ions can be used for enhancement of solar cells efficiency. The general scheme showing the principle of operation of down-conversion layer based on Gd2O3: Er was presented. The concentration dependences of emission intensity and energy transfer efficiency were obtained.
