A P 2 O 5 -CaO-SrO-BaO phosphate glass doped with Tm 3+ and glasses doped with (Tm 3+ , Pr 3+ ) were used for this study. The photo-luminescence behaviors of Tm 3+ and Pr 3+ in phosphate glass were investigated by absorption, excitation and emission spectroscopy. The energy transfer between Tm 3+ and Pr 3+ in phosphate glasses...
In this paper, we present the photoluminescence properties of Pr 3+ , Sm 3+ and Er 3+ doped phosphate glasses. Optical absorption and emission spectra of lanthanide active ions in P 2 O 5 –CaO–SrO–BaO glass have been investigated at room temperature. These glasses have shown strong absorption bands in the near-infrared (NIR) and visible (VIS) region. For Pr...
