摘要：
RE3+ (RE3+ = Tm3+, Dy3+) ion single and co-doped tungsten borate glasses for white light emitting diodes (LEDs) were prepared by melt quenching method. Emission and excitation spectra of the glasses were measured. The color of luminescence can be tuned by changing the composition of glass matrix or the concentrations of Tm3+ and Dy3+ ions. White light emission can be achieved from 0.5 Dy3+ single-doped 15WO(3)-25La(2)O(3)-60B(2)O(3) and 0.4Tm(3+)/1.5Dy(3+) co-doped 50WO(3)-25La(2)O(3)-25B(2)O(3) glasses. In addition, energy transfers between Tm3+ and Dy3+ were also analyzed. The Dy3+/Tm3+ co-doped tungsten borate glasses may be potential candidates for white LED application. (C) 2014 Elsevier B.V.
