摘　　要：白光LED以其独特优势被称为第四代光源,具有广阔的应用前景。单一基质白光荧光粉(SMWP)因颜色稳定、色彩还原性好,成为白光LED用光转换材料的研究热点。概述了由近紫外LED芯片激发的白光荧光粉的研究现状,指出了该荧光粉存在的问题并对其发展趋势做了展望。White LEDs is mentioned as the fourth generation illuminate lamp for its advantages, which will be widely used. The single matrix white light emitting phosphor（SMWP） becomes the focus of light-conversion materials＇ research because of its stability of color and good property of color deoxidization. The present research situation of white light-emitting phosphors in single matrix excited by near ultraviolet LED were introduced. The problems existing in the phosphors were pointed out and a brief prospect of WLEDs was made.
