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.
