Luminescence Characteristics of Li₂O₃:Gd₂O₃:B₂O₃:Dy₂O₃ Glasses System

Abstract:

Melt quenching technique have been used to prepare the dysprosium-doped lithium-gadolinium borate glasses, which have the composition [60Li₂O:10Gd₂O₃:(30-x) B₂O₃:xDy₂O₃] (LGBO:Dy³⁺), under atmospheric pressure. Some properties: density, molar volume, absorption spectra and photoluminescence of the LGBO:Dy³⁺glasses were investigated and discussed. The density of glasses drops to the minimum point at 0.05 mol% and swings after that point. The molar volume of the glasses does not depend on Dy₂O₃concentration. In absorption spectra for the range of visible to near infrared wavelengths, there are 5 obvious peaks indicating the Dy³⁺ in glass network. The intensity of each peak at certain wavelength increases with concentration of the Dy₂O₃. Whereas the excitation spectra show 7 obvious peaks representing the transitions from the ground state⁶H_15/2to various excited states. The Xenon compact arc lamps were used to measure the emission spectra with 388 nm light. As the result, the LGBO:Dy³⁺ glass sample with 0.50 mol% of Dy³⁺ shows the highest intensity in the emission spectra.
