摘要：Tb3+ ions doped and Tm/Tb/Sm co-doped glasses for light-emitting-diodes (LED) applications have been synthesized by melt quenching method. Their photoluminescence properties were studied by emission and excitation spectra. The D-5(3) and D-5(4) emission of Tb3+ can be varied by adjusting Tb3+ concentrations and the compositions of glass matrix. Blue, green and reddish orange emission bands were observed in the emission spectra of Tm/Tb/Sm co-doped glasses. The combination of these emission bands allows the realization of white light when the glasses are excited by near ultraviolet light. In addition, the relative intensity ratios of respective emission lines are dependent on the composition of glasses and the excitation wavelength. (C) 2009 Elsevier B.V. All rights reserved.
