title: Facile Preparation and Ultrastable Performance of Single-Component White-Light-Emitting Phosphor-in-Glass used for High-Power Warm White LEDs.
abstract: 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.
