Luminescent characteristics of LiSrBO3:M (M=Eu3+, Sm3+, Tb3+, Ce3+, Dy3+) phosphor for white light-emitting diode

Abstract LiSrBO 3 :M (M = Eu 3+ , Sm 3+ , Tb 3+ , Ce 3+ , Dy 3+ ) 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.
