摘　　要：白光LED具有低压、低功耗、高可靠性和长寿命等一系列优点,是一种符合节能环保的绿色照明光源。现阶段的白光LED显色指数低、色温较高,限制了白光LED在室内照明等领域的发展,而红色荧光粉能对白光LED的显色指数的提高及色温的改善影响极其显著。主要介绍白光LED用红色荧光粉几大主要体系的发光性质及最新发展现状。White LED is an environmental protection and energy-saving green color lighting,which had a series of advantages such as a low voltage,low power consumption,high reliability and long life.Nowadays the white LED which color rendering index is low,and higher color temperature,limiting the development of white LED.However the the red emitting phosphor will increase the color rending index and improve the color temperature of the white LED extremely.Reviewed latest development and Luminescence of varieties of red-emitting phosphor used in white LED.
