This paper reports the concentration effect of Europium (Eu3+) ion doped lithium zinc borosilicate (LZBS) glasses for laser applications. Through the melt quenching process, these glasses were prepared. Different physical properties such as oxygen packing density (O), average molecular weight (M), rare earth ion concentration (N), inter-ion distance (ri), field strength (F), molar volume (Vm), molar refractivity (Rm), reflection loss (R) and metallization (R) were calculated in the prepared LZBS glasses. The oscillator strengths experimental (fexp) and calculated (fcal) of the absorption bands originating from the ground (7F0) and the first excited (7F1) states of Eu3+ion are discussed. The Judd - Ofelt intensity (J-O) parameters (Ω2, Ω4, and Ω6) were assessed from the absorption spectra by applying thermal correction to the doped glasses of Eu3+. For the transition 5D0→7Fj, j, J = 0,1,2,3, and 4 of the Eu3+ ion, the J-O parameters (Ω2, Ω4, and Ω6) are further used to measure radiative parameters such as transition probabilities (AR), branching ratio (βR), stimulated emission cross-section (σe) and radiative life period (τR). For the prepared glasses, decay analysis was performed for different concentrations of Eu3+ ions.
