The recent development of light-emitting diodes (LEDs) using remote phosphors to generate white light has seen this family of devices become well-positioned to replace conventional lighting. They offer higher efficiencies compared to traditional bulbs and do not contain toxic mercury, as with fluorescent lamps. However, the color quality of the light emitted from commercial white LEDs, which is typically bluish, is not yet comparable to that of incandescent lamps. In this Perspective, we discuss the potential application of luminescent metal clusters confined inside of zeolites as remote phosphors for designing warm white LEDs. Such materials may not only improve the LEDs’ light quality but also help maintain device stability and efficiency, compared to other LED phosphors. Moreover, in terms of optical properties and stability of metal-loaded zeolites, the necessary improvements and drawbacks are identified, and viable solutions—through rational design protocols—are outlined.

使用远程磷光体产生白光的发光二极管（LED）的最新发展已经看到，该系列设备已准备就绪，可以替代传统照明。与传统灯泡相比，它们具有更高的效率，并且不像荧光灯那样包含有毒的汞。但是，从商业白色LED发出的光的颜色质量通常是带蓝色的，尚不能与白炽灯相媲美。在此“观点”中，我们讨论了限制在沸石内部的发光金属团簇作为远程荧光粉在设计暖白光LED方面的潜在应用。与其他LED荧光粉相比，此类材料不仅可以改善LED的光质量，而且还有助于保持器件的稳定性和效率。而且，
