CsPbX3 (X = Cl, Br, I) perovskite quantum dots (QDs) have emerged as competitive candidate luminescent materials in the photoelectric fields due to their superior luminescence properties. However, the major drawback such as poor resistance to temperature, moisture, and irradiation of light, especially for the red QDs with I–, hinders their practical applications. Herein, we synthesized Mn2+-doped CsPbCl3 embedded in the cage of zeolite-Y as a new orange-red phosphor for the white light-emitting diode (WLED). The composites have significantly improved resistance to both elevated temperature and water over the bare Mn2+-doped QDs. The former exhibits little degradation whereas the latter shows apparent decline upon the irradiation of lights in the orange LED devices, which are fabricated by employing each material as a color-conversion phosphor coated on a 365 nm UV chip. A WLED is also achieved with a 365 nm UV chip coated with a CsPb(Cl0.5,Br0.5)3–Y blue phosphor and a CsPb0.75Mn0.25Cl3–Y orange phosphor. The device possesses a Commission Internationale de l’Éclairage coordinate of (0.34, 0.36), a correlated color temperature of 5336 K and a color rendering index of 81.

将Mn 2+掺杂的卤化铅钙钛矿限制在Zeolite-Y中，作为用于白色发光二极管的超稳定的橙红磷光体复合材料
CsPbX 3（X = Cl，Br，I）钙钛矿量子点（QDs）由于其卓越的发光性能已成为光电领域中竞争性的候选发光材料。然而，主要缺点，例如对温度，湿度和光照射性差，特别是对于与I红色量子点- ，阻碍了它们的实际应用。在本文中，我们合成了嵌入在Y型沸石笼中的Mn 2+掺杂的CsPbCl 3作为用于白色发光二极管（WLED）的新的橙红色荧光粉。该复合材料在裸露的Mn 2+上具有显着改善的耐高温和耐水性能掺杂的量子点。前者几乎没有降解，而后者在橙色LED器件中受到光的照射后明显下降，橙色LED器件是通过将每种材料用作涂在365 nm UV芯片上的颜色转换磷光体而制成的。使用涂有CsPb（Cl 0.5，Br 0.5）3 -Y蓝色荧光粉和CsPb 0.75 Mn 0.25 Cl 3 -Y橙色荧光粉的365 nm UV芯片也可以实现WLED 。该设备具有（0.34，0.36）的国际照明委员会坐标，相关色温5336 K和显色指数81。
