Luminescence Properties of Ytterbium Activated PLZT Ceramics
Abstract
<jats:p>In the present work the influence of co-doping with ytterbium ions (for 0, 0.5, 1.5, 2.5 wt.% of Yb<jats:sup>3+</jats:sup>) on physical properties of 8/65/35 PLZT was studied. The ceramic powders were synthesized by the modified sol-gel method, and underwent consolidation by the pressure-less sintering techniques, in <jats:italic>Ts</jats:italic>=1200°C/6h. Our investigations give a detailed account of the relationships between concentrations of trivalent ytterbium ions in PLZT matrix, on their structure, microstructure, as well as luminescence properties. Near-infrared luminescence spectra at about 1020 nm were registered, which correspond to <jats:sup>2</jats:sup>F<jats:sub>5/2</jats:sub> - <jats:sup>2</jats:sup>F<jats:sub>7/2</jats:sub> transition of Yb<jats:sup>3+</jats:sup>. Based on decay measurements, the luminescence lifetimes for the <jats:sup>2</jats:sup>F<jats:sub>5/2 </jats:sub>excited state of Yb<jats:sup>3+</jats:sup> were determined. Luminescence decay analysis indicates that the <jats:sup>2</jats:sup>F<jats:sub>5/2</jats:sub> lifetime increase with increasing activator concentration (Yb<jats:sup>3+</jats:sup>) in PLZT ceramic matrix.<jats:italic /><jats:italic /></jats:p>
