Abstract
Low thermal quenching and high-efficiency Ca3Sc 2Si3O12:Ce3+ (CSSO:Ce3+) phosphors with co-doping Tb3+ ion were prepared by a solid state method and the properties of these phosphors were investigated. The results showed that co-doping of Tb3+ not only enhances the photoluminescence remarkably and decreases the thermal quenching of the phosphor, but also heightens the performances of the LEDs fabricated with the phosphor. A high-efficiency and low color temperature white LED was fabricated with the prepared CSSO:1%Ce3+, 0.5%Tb3+ and a red phosphor, indicating that CSSO:1%Ce3+,0.5%Tb3+ phosphor is a suitable green phosphor for the fabrication of high-efficiency white LEDs.
