摘要
LiSrBO3:M (M = Eu3+, Sm3+, Tb3+, Ce3+, Dy3+) phosphors which have been developed for white light-emitting diodes (LEDs) were synthesized by a normal solid-state reaction. The emission and excitation spectra indicate that these phosphors can be effectively excited by near-ultraviolet light-emitting diodes (UVLED), and exhibit satisfactory red, green and blue performances, respectively, nicely fitting in with the widely applied UV chip. Under the condition of doping charge compensation Li+, Na+ and K+, the luminescence intensities of these phosphors were increased. (C) 2009 Elsevier Ltd. All rights reserved.
