High Thermal Stability Apatite Phosphors Ca₂La₈(SiO₄)₆O₂:Dy³⁺/Sm³⁺ for White Light Emission: Synthesis, Structure, Luminescence Properties and Energy Transfer.

ABSTRACT: What ideal w-LED phosphors always aim to do is to achieve a single phase near-sunlight emission phosphor simultaneously with both high luminescence efficiency and high thermal stability at operation temperature. And It is well known that apatite compound phosphors are one of the most promising optical materials to realize those above because of their unique structure enhanced luminescence properties and thermal stability. Here, we synthesized a co-doped single phase apatite phosphors Ca₂La₈(SiO₄)₆O₂:Dy³⁺/Sm³⁺ (CLSO:Dy³⁺/Sm³⁺) for white light emission, which was provided with excellent thermal stability and of which luminescence intensity at 150 °C still was 92 percentage of that at room tempe
