白光LED具有低压、低功耗、高可靠性和长寿命等一系列优点,是一种符合环保和节能的绿色照明光源。现阶段制造高显色指数、低色温,大功率白光LED是白光LED发展的总体趋势。而红色荧光粉性能对白光LED的显色指数及色温的影响极其显著。本方法着重介绍和评述了白光LED用红色荧光粉硫化物、氮化物、钼酸盐和钨酸盐等几大主要体系的发光性质及最新研究成果和发展现状,并对白光LED用荧光粉的发展进行了展望。
White LED with a series of advantages of low voltage, low power consumption, high reliability and long life, is a green light source that is environmentally friendly and energy saving. At this stage to create high color rendering index, low color temperature, high-power white LED is the overall trend of white LED development. The red phosphor performance of white LED color rendering index and color temperature is extremely significant. This method focuses on the introduction and review of the luminescence properties and the latest research results and development of several major systems such as red phosphor sulfide, nitride, molybdate and tungstate for white LED. Development prospects.
