An addition of Eu³⁺ ions in Borate glasses (7TiO₂ + 3Al₂O₃ + (60−x)B₂O₃ + xEu₂O₃ + 5LiCO₃ + 25SrCO₃) (where x = 0.05, 0.10, 0.15, and 0.20 mol%) and Boro-phosphate glasses (40B₂O₃ + 3Al₂O₃ + (10−x)P₂O₅ + xEu₂O₃ + 7ZnO + 5LiCO₃ + 10H₆NO₄P + 25SrCO₃) (where x = 0.10 and 0.20 mol%) containing heavy metals, alkali, and alkaline were prepared using a conventional melt quenching technique. The complementary study of the FT-IR and FT-Raman spectroscopic studies proposed the conversion of BO₃ ⇔ BO₄ in the borate glass network, and the exchange of the PO₃ ⇔ PO₂ in the boro-phosphate glass network by increasing the Eu³⁺ ion concentration. The optical characteristics including absorption, linear refractive index (n), Urbach energy (E_u), direct and indirect band gap energies of the prepared glasses were examined and discussed. Judd-Ofelt (JO) theory was used to determine radiative spectroscopic properties such as radiative transition probability (A_R), luminescence branching ratio (β_R) and stimulated emission cross-section $\left({\sigma }_P^E\right)$. Theoretically, the optical gain parameter and gain bandwidth were calculated, which shows their vital role in laser applications. Using CIE chromaticity coordinates, the reddish orange light emission was observed as a proportion of the increase in Eu³⁺ ions concentration in both glass networks. The measured colour coordinates were utilised to evaluate the correlated colour temperature (CCT), colour purity (P_c), and excitation purity (P_e) of the studied glasses.
