In this present work, single Sm³⁺ ion-activated Ca₂LaNbO₆ phosphors were successfully synthesized by simplify solid-state reaction method. The X-ray diffraction (XRD) patterns, X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDS), elemental mappings, and some other characterizations were presented. The photoluminescence emission (PL) and excitation (PLE) spectra were recorded, and the optimum doping concentration was 5 mol% while the mechanism of concentration quenching was predominant by the diploe-diploe interaction. The optimal Ca₂LaNbO₆:0.05Sm³⁺ phosphor exhibited near red region with good thermal stability and lifetime. Eventually, the packaged white-LED device was achieved with a forward current of 300 mA, it could emit a dazzling white light with high CRI value of 86.87, revealing that Ca₂LaNbO₆: Sm³⁺ phosphors could be promised for high CRI white communication.

在本工作中，通过简化的固态反应方法成功地合成了单个Sm ³⁺离子激活的Ca ₂ LaNbO ₆荧光粉。介绍了X射线衍射（XRD）模式，X射线光电子能谱（XPS），能量色散X射线能谱（EDS），元素映射以及其他一些特征。记录了光致发光发射（PL）和激发（PLE）光谱，最佳掺杂浓度为5 mol％，而浓度猝灭的机理主要是由二倍体-双倍体相互作用引起的。最佳Ca ₂ LaNbO ₆：0.05Sm ³⁺磷光体显示出红色区域，具有良好的热稳定性和寿命。最终，封装的白光LED器件通过300 mA的正向电流实现，它可以发出令人眼花white乱的白光，具有86.87的高CRI值，表明Ca ₂ LaNbO ₆：Sm ³⁺磷光体有望实现高CRI白光沟通。
