摘要：
Recently developed nitride/oxynitride phosphors are promising candidates for a white light-emitting diode. beta-SiAlON:Eu, Ca-alpha-SiAlON:Eu and CaAl-SiN3:Eu phosphors are able to be excited by blue light and emit green, yellowish orange and red light, respectively. High brightness warm-white LED lamps of over 50 Im/W luminous efficacy have been realized by combination of a blue LED die and Ca-a-SiAlON:Eu. High color-rendering index white LED lamps of over Ra 80 have been also realized using the three color phosphors.
