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 ¹D₂→³H₄ 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.
