Spectroscopic Investigations on Pr3+ Doped Alkali Fluoroborophosphate Glasses
B. Rupa Venkateswara Rao*, M.V.V.K. Srinivas Prasad, L. Tanuj Kumar, M. Venkateswarlu


Alkali fluoroborophosphate glasses doped with praseodymium fluoride has been prepared and characterized by X-Ray diffraction, UV–Visible spectroscopy, differential scanning calorimetry, excited and emission spectra analysis. Judd-Ofelt theory has been applied to evaluate the optical parameters such as radiative transition probabilities, radiative lifetime, branching ratios etc. of praseodymium, Pr3+, ions. The trend found in the JO intensity parameter is Ω6> Ω4> Ω2, it indicates the glass system is favorable for the lasing emission 1D23H4 in IR wavelength. Among the studied glasses, the glass with 20 mole% of NaF appears to be an ideal material for carrying out further investigations on samples of appropriate size to examine laser action to use them in glass laser technology and optical communications.
