Absorption Spectrum Analysis to Predicted and Calculated the Spectroscopic Properties of Pr:SiO2

Hanaa M. Yaseen

Abstract: Spectroscopic properties of Pr:SiO2 samples have been investigated at room temperature, the samples are prepared by using Sol Gel method. Theory of Judd-Ofeltt is used to analysis the UV- Visible spectra (in range of 400-900nm) and to calculate the three Judd-Ofeltt of parameters; ? 2, ? 4 and ? 6. From the obtained parameters, the radiative transition probabilities A(J;J?), radiative lifetime ?rad and branching ratio ?_(J ?J`) are calculated. The suitable values of A(J;J?), ? r a d and ?_(J ?J`) could be lead to suggests P r : S i O 2 as optical material for Laser action.
