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，白光LED创新的进一步发展和大规模应用一直受到当前红色荧光粉效率的限制。尽管碱土硫化物(AES)红色荧光粉是一种很有前途的白光LED候选材料，但其较低的化学稳定性阻碍了其应用。该项目旨在开发用于白光LED的新型化学稳定的氮化硼保护的AES荧光粉纳米复合材料。预期的结果将为克服目前的荧光粉稳定性问题提供有效的战略，并将满足白光LED应用对优质红色发光材料的迫切需求。

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.
