ABSTRACT
To the best of our knowledge, we have successfully fabricated a novel transparent ceramic phosphor of Pr3+-doped Ba (Sn, Zr, Mg, Ta) O3 (Pr3+BMT) via a high-temperature solid-state reaction method. The in-line transmittance of 59% at 650 nm was measured. The Pr3+BMT ceramic phosphor can emit 650 nm red light excited by 447 nm blue light. The ceramic phosphor can still work at 383 K. The activation energy was calculated to be 0.17 eV. The efficiency of the ceramic phosphor is twice that of its powder phosphor. The Pr3+BMT ceramic phosphor showed good thermal stability and enhanced the chromaticity of its white LEDs, which make it a promising red phosphor for lighting.
