In this work, a phosphor for white light-emitting diode (LED) application, Ce³⁺-doped yttrium aluminum garnet (YAG:Ce³⁺), was successfully packaged using a P₂O₅-ZnO-Na₂O-Al₂O₃ glass-ceramic system, through a vertical deposition method. Here, we found that white light can be achieved by combining the packaged phosphor with a blue chip (e.g. InGaN). The specimen doped with 4 mol% Al₂O₃ showed a luminous efficacy (LE) of 125.8 lm W⁻¹, at a correlated color temperature (CCT) of 5769 K, with a color rendering index (CRI) of 68. In addition, the LE loss of the specimen doped with 4 mol% Al₂O₃ was only 3.6% after heat treatment at 150 °C for 1200 h, which is significantly lower than that of traditional resin (19.3%). Moreover, a possible mechanism for reducing the LE loss using glass-ceramics was proposed.

在这项工作中，成功地使用P ₂ O ₅ -ZnO-Na ₂ O-Al包装了用于白色发光二极管（LED）的荧光粉，掺杂Ce ^3+的钇铝石榴石（YAG：Ce ³⁺）。₂ O ₃玻璃陶瓷系统，通过垂直沉积方法。在这里，我们发现可以通过将封装的荧光粉与蓝色芯片（例如InGaN）结合使用来获得白光。掺有4 mol％Al ₂ O ₃的样品的发光效率（LE）为125.8 lm W ^-1，在相关色温（CCT）为5769 K时，显色指数（CRI）为68。此外，掺有4 mol％Al ₂ O ₃的样品在150°C热处理后的LE损耗仅为3.6％。 150°C持续1200 h，大大低于传统树脂的温度（19.3％）。此外，提出了一种使用玻璃陶瓷减少LE损耗的可能机制。
