A series of new borophosphate-based phosphors KSrBP2O8 (KSBP):Sm3+ with different samarium concentrations were synthesized using a facile sintering synthesis. The powder purity, morphology, and photoluminescence were thoroughly performed. Meanwhile, concentration quenching and thermal quenching for luminescent properties were discussed. The orange-red luminescence with a millisecond-level short lifetime and high thermal stability is obtained from the prepared phosphor, which is excited by the near-ultraviolet wavelength of 400 nm. The result demonstrates a promising borophosphate-based phosphor for advanced lighting and displays.

钐 (Ⅲ) 活化的 KSrBP2O8 硼磷酸盐的热稳定橙红色发光
使用简便的烧结合成法合成了一系列具有不同钐浓度的新型硼磷酸盐基磷光体 KSrBP 2 O 8 (KSBP):Sm 3+。对粉末纯度、形态和光致发光进行了彻底的测试。同时，讨论了发光特性的浓度猝灭和热猝灭。制备的荧光粉在400 nm的近紫外波长激发下，获得了具有毫秒级短寿命和高热稳定性的橙红色发光。结果证明了一种用于高级照明和显示器的有前途的基于硼磷酸盐的磷光体。
