  Ln2O3 doped PbO-NaF-B2O3 glasses were prepared and characterized through spectroscopic technique such as photoluminescence at room temperature to derive luminescence properties of Ln3+ ions in these glasses. Radiative properties which include radiative transition possibilities, branching ratios, radiative lifetime and stimulated emission cross sections of the fluorescent degree of Ln3+ ions in titled glasses are determined. In the present work all our systematic analysis has been presented with an example of results obtained in PbO-NaF-B2O3-Ln2O3 glasses. These results are used to access the gain media and in turn useful not only to write waveguides but also to modify the fluorescence properties through laser irradiation... Read More»
