摘　　要：根据蓝光芯片的发光特性,从激活剂、助熔剂、基质Y3+的替代物等方面较系统地研究了YAG∶Ce3+荧光粉的制备。最终的荧光粉产品制成5mm封装20mA蓝光激发的白光LED后,光效可达70 lm/W,显色指数≥80。In order to develop white light LED for general lighting,based on the luminescence characteristics of blue chips,a more systematic study of the preparation of YAG： Ce3＋ phosphor（including activator,fluxing agent,substitutes for Y3＋ etc.） has been conducted.The luminous efficiency of 5mm 20mA w-LED made by final phosphor is up to 70lm/W and its CRI ≥ 80.
