Abstract
Judd-Ofelt parameters for Pr 3+ ions in zinc borosulphate glass (ZBS) and alkali zinc borosulphate glasses (RZBS, R = Li, Na, K or Gd) were derived from the intensities of the integrated absorption bands. The radiative transition probabilities A, radiative lifetimes τ r, branching ratios β R and integrated emission cross sections σ a were calculated for the excited states 3P 0, 3P 1 and 1D 2. The resulting spectroscopic parameters are compared with the corresponding reported values.
