摘要:
The Eu3+-doped red-orange emitting phosphor of tellurite glass 0.25Li(2)O-0.20Y(2)O(3)-0.5TeO(2)-0.05Eu(2)O(3) has been synthesized by the melt quenching method. The amorphous nature of the glass has been verified by XRD measurements. The photoluminescence excitation and emission spectra, the luminescence decay curves have been investigated for the composition. The phosphor can be efficiently excited by the near UV light to realize the intense narrow red emission line (611 nm) corresponding to forced electric dipole transition D-5(0) -> E-7(2) of Eu3+ ions. The Li2O-Y2O3-TeO2:Eu(3+)glass phosphor is a potential red-orange emitting candidate for the application in WLEDs. (C) 2014 Elsevier B.V. All rights reserved.
