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 Y0.8 Tb0.2AG: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.
