As a promising color converter in warm white LEDs, phosphors-in-glass (PiG) thick film is still suffering from the deficiency of high-efficient red phosphors. Herein, commercial Ce³⁺: Y₃Al₅O₁₂ and/or Eu²⁺: Sr₂Si₅N₈ phosphors were successfully embedded into a phosphate glass matrix coated on a soda-lime-silicate glass substrate. Their structural and luminescent properties were respectively investigated by XRD, SEM and photoluminescence spectra analysis. Color-tunable emission was achieved by varying the weight ratio of red to yellow phosphors. After fabricating LED devices with the optimal sample, considerable luminous performance was achieved with luminous efficacy of 72.1 lm/W, correlated color temperature of 5612 K and color rendering index Ra of 82.5. It suggested that the Ce³⁺: Y₃Al₅O₁₂/Eu²⁺: Sr₂Si₅N₈ PiG thick film exhibits a significant potential for high-power warm white LEDs.

作为温暖的白色LED中有希望的颜色转换器，玻璃荧光粉（PiG）厚膜仍遭受高效红色荧光粉缺乏的困扰。在此，商品Ce ³⁺：Y ₃ Al ₅ O ₁₂和/或Eu ²⁺：Sr ₂ Si ₅ N ₈将磷光体成功地嵌入涂覆在钠钙硅酸盐玻璃基板上的磷酸盐玻璃基质中。通过XRD，SEM和光致发光光谱分析分别研究了它们的结构和发光性能。通过改变红色和黄色荧光粉的重量比可以实现颜色可调的发射。用最佳样品制造LED器件后，获得了可观的发光性能，发光效率为72.1 lm / W，相关色温为5612 K，显色指数Ra为82.5。这表明Ce ³⁺：Y ₃ Al ₅ O ₁₂ / Eu ²⁺：Sr ₂ Si ₅ N ₈ PiG厚膜对于高功率暖白光LED具有巨大的潜力。
