Neodymium strontium bismuth borate glass samples were prepared using the traditional technique of high-temperature melting. The optical absorption spectra of the studied samples were recorded at room temperature. Analyzing the recorded spectra, important optical parameters were determined; for example, refractive index, optical dielectric constant, the indirect optical band gap and Urbach energy. The calculated Judd-Ofelt parameters exhibited trend which is Ω 2 >Ω 6 >Ω 4 . Moreover, the experimental and calculated oscillator strengths f , exp f cal of the radiative 4f transitions, their lifetimes τ, refractive indices n, the emission, absorption cross sections ( ) s l , abs ( ) s l emis and the branching ratio β were all determined and investigated. Calculations of the optical gain coefficient ( ) l G for all emission peaks revealed the possibility to use the present glass in laser emission materials and optical communication applications.

“…The O/R ratio for the current samples was found to be 2.82, 2.72, 2.95, and 2.98 for samples BPbSrWSm 0.5 , BPbSrWSm 1.0 , BPbSrWSm 2.5 , and BPbSrSm 3.0 , respectively. The obtained values for the studied glass were higher than in previous reports [33][34][35][36]. These values indicated high asymmetry of the lattice around the Sm 3+ ions.…”

In this study, the melt quenching approach is used to synthesize a lead borate–strontium‐based glass system doped with samarium ions. Modifications in the glass network structure arising from the addition of various concentrations of Sm3+ ions were investigated via Fourier transform infrared (FTIR) spectroscopy. FTIR analysis revealed B–O–B bridges, BO3, and BO4 units are present. UV–vis–NIR spectroscopic measurement was performed to study the optical absorption spectra. Optical constants such as optical bandgap energies, refractive indices, and other related parameters were evaluated. The lifetime fluorescence decay was measured and ranged between 1.04 and 1.88 ns. The photoluminescence spectra in the range 500–750 nm revealed four transitions from the ground state 6G5/2 to the excited states 6H5/2, 6H7/2, 6H9/2 and 6H11/2 and J–O theory was utilized to study these optical transitions for Sm3+ ions. Calculations of the oscillator strengths and J–O intensity parameters were performed and the obtained J–O parameters followed the sequence Ω4 > Ω6 > Ω2. The ratio O/R indicated a high lattice asymmetry around the samarium ions. The values of lifetimes and branching ratios for the fabricated samples emphasized their suitability to be used in laser applications. The current glass samples are good candidates for orange and red emission devices.
