中文摘要	we fabricated a phosphor-conversion white light using an ingan laser diode that emits 405 nm near-ultraviolet (n-uv) light and phosphors that emit in the blue and yellow regions when excited by the n-uv and blue light, respectively.the relationship of the luminous flux and the luminous efficacy of the white light with injection current was discussed. the luminous flux increased linearly with increasing current above the threshold of the laser diode, and at 80 ma injection current, the luminous flux and luminous efficacy were estimated to be 5.7 lm and 13 lm/w, respectively. the shift of the commission international de i'eclairage coordinates, color temperature, and color rendering index with current are very slight and negligible, which indicates that the blue and the yellow phosphors have an excellent stability and a highly stable white light can be obtained by this way.
