Abstract

The paper investigates the effect of co-doping Tb³⁺ as an energy-transfer sensitizer on optical properties of YAG:Re³⁺ (where, Re = Ce, Eu) phosphor films synthesized by sol-gel route. The results suggest that, Tb³⁺ is a promising sensitizer for improving the optical performances of the as-prepared YAG:Re³⁺ films, and a Tb³⁺ co-doping concentration of 20% was found to be an optimum level on account of Tb³⁺ concentration quenching. Due to the energy-transfer processes of Tb³⁺→Re³⁺, the as-prepared Y_0.8 Tb_0.2AG:Re³⁺ films displayed strong abilities of absorption in the ultraviolet (UV) light range, and bright green-yellow emission for YAG:Ce³⁺ or red emission for YAG:Eu³⁺ under 275 nm irradiation, which could be utilized for UV-excited WLED and display applications.
