长寿命、优异的色稳定性以及易于获得的白光正成为最先进的高功率白光LED面临的三大突出挑战。这项研究首次探索了一种新型单组分白光发射玻璃磷光体（PiG）。它的量子效率高达26.2%，并具有传统荧光粉浆料中很少报道的优异耐热性和良好的耐湿特性。通过将 PiG 与近紫外板载芯片 (n-UV COB) 相结合，制造了概念验证暖白光 LED。这封信中报道的这种方法将为先进高功率白光 LED 提供一种新的、简单的方法来获得性能优异的单组件发光转换器。
Long lifetime, excellent chromatic stability, and easily obtainable white light are becoming three outstanding challenges faced by the state-of-the-art high-power white LEDs. This study explored a novel single-component white-light emitting phosphor-in-glass (PiG) for the first time. It has a quantum efficiency of 26.2% and exhibits excellent heat resistance and good humidity-resistance characteristics which are rarely reported in traditional phosphor slurry. A proof-of concept warm white LEDs was fabricated by combining PiG with near-ultraviolet chip-on-board (n-UV COB). This method reported in this letter will open a new and simple approach to obtain excellent performance single-component luminescent convertor for advanced high-power white LEDs.
