Abstract
- Fluoroindate glasses co-doped with Pr<superscript>3+</superscript>/Er<superscript>3+</superscript> ions were synthesized and their near-infrared luminescence properties have been examined under selective excitation wavelengths. For the Pr<superscript>3+</superscript>/Er<superscript>3+</superscript> co-doped glass samples several radiative and nonradiative relaxation channels and their mechanisms are proposed under direct excitation of Pr<superscript>3+</superscript> and/or Er<superscript>3+</superscript>. The energy transfer processes between Pr<superscript>3+</superscript> and Er<superscript>3+</superscript> ions in fluoroindate glasses were identified. In particular, broadband near-infrared luminescence (FWHM = 278 nm) associated to the <superscript>1</superscript>G<subscript>4</subscript> → <superscript>3</superscript>H<subscript>5</subscript> (Pr<superscript>3+</superscript>), <superscript>1</superscript>D<subscript>2</subscript> → <superscript>1</superscript>G<subscript>4</subscript> (Pr<superscript>3+</superscript>) and <superscript>4</superscript>I<subscript>13/2</subscript> → <superscript>4</superscript>I<subscript>15/2</subscript> (Er<superscript>3+</superscript>) transitions of rare earth ions in fluoroindate glass is successfully observed under direct excitation at 483 nm. Near-infrared luminescence spectra and their decays for glass samples co-doped with Pr<superscript>3+</superscript>/Er<superscript>3+</superscript> are compared to the experimental results obtained for fluoroindate glasses singly doped with rare earth ions.
