BaMg2Al16O27:Eu, SrGa2S4:Eu, and ZnCdS:Ag,Cl phosphors were chosen to produce blue, green, and red emissions, respectively, under excitation from a violet light emitting diode (LED). A four-band white LED was obtained by a combination of nonabsorbed violet emission from a violet LED and blue, green, and red emissions from BaMg2Al16O27:Eu, SrGa2S4:Eu, and ZnCdS:Ag,Cl phosphors. The luminescent properties of the four-band white LED were also discussed. Keywords: White LED, Luminescent property. (LED; light emitting diode) >?! :; @ * AB$ C% D EF% GH IJ" *KFL.
