摘要：
A SrGa2S4:Eu phosphor was synthesized using a decomposition method without the use of toxic H2S gas. SrGa2S4:Eu and ZnCdS:Ag,Cl phosphors were chosen to produce green and red emissions, respectively, under excitation from a blue light emitting diode (LED). A three band white LED was obtained through a combination of nonabsorbed blue emission from a blue LED and green and red emissions from the SrGa2S4:Eu and ZnCdS:Ag,Cl phosphors. The optical properties of the three band white LED are also discussed. (C) 2003 The Electrochemical Society.
