英文摘要	Tremendous progress has been achieved in white light-emitting diodes (leds). to further improve the quality of white light and simplify the fabrication process, a single chip white-light led with the ingan underlying layer (ul) was studied and fabricated. the turn-on voltage of this type of led was 2.7 v, and the spectrum at a forward bias current of 20 ma was comprised of blue (443 nm) and yellow (563 nm) lights. the intensity ratio of blue to yellow light was almost constant with the increasing injection current in a certain scope, most important for the solid state illumination. the useful life test showed the light output level remained at a 90% light output level at the driving current of 40 ma after 300 h, meanwhile, the uv and blue leds combined with phosphor reached a 20% value after 144 h within 300 h.
