Development of new chemically stable boron nitride-protected phosphor nanocomposites for white light-emitting diodes

白色发光二极管（LED）被认为是下一代固态照明的关键。然而，白色LED创新的进一步发展和大规模应用受到当前发红光磷光体的效率的限制。虽然碱土金属硫化物（AES）红色荧光粉是白色LED的有希望的候选者，但是AES的低化学稳定性阻碍了其利用。该项目旨在开发用于白色LED的新型化学稳定的氮化硼保护AES磷光体纳米复合材料。预期的结果将提供一个有效的策略，以克服目前的磷光体的稳定性问题，并将满足白色LED应用的上级红色发光磷光体的迫切需求。

White light-emitting diodes (LEDs) are considered the key to next-generation solid-sate lighting. However, further advancements and the large-scale application of white LED innovation has been restricted by the efficiency of current red-emitting phosphors. Although alkaline earth sulphide (AES) red phosphor is a promising candidate for white LEDs, the low chemical stability of AES hinders its utilisation. This project aims to develop new chemically stable boron nitride-protected AES phosphor nanocomposites for white LEDs. The expected outcomes will provide an effective strategy to overcome current phosphor stability problems, and will meet the urgent demand for superior red-emitting phosphors for white LED applications.
