A series of glass compositions (60-x) B2O3-10TeO(2)-15BaCO(3)-15MgF(2)-xEr(2)O(3) with diverse quantities of erbium ions (Er3+) was synthesized using the melt quenching method and the samples were subjected to thorough characterization to explore their optical and structural properties. In order to ascertain the amorphous nature of the glass and acquire a deeper understanding of its chemical bonding, conventional methods of characterization, such as X-ray diffraction and Fourier transform infrared spectroscopy, were utilized. The Judd-Ofelt intensity parameters were computed using the absorption spectra of glasses doped with Er3+, providing vital information about the local environment and coordination of Er3+ ions in the glass matrix. The glasses underwent the collection of near -infrared (NIR) emission spectra. Following this, an analysis was carried out to look into and understand the spectral properties, emission cross-section, and gain coefficient parameters of the glasses. The spectra obtained discernible characteristics, notably a significant near-infrared (NIR) band associated with the transition between the I-4(13/2) and I-4(15/2) states. This band was seen to have a central wavelength of 1530 nm. This emission band spanned the wavelengths commonly used in optical communication systems (S + C) -bands, making these glasses suitable candidates for applications such as wavelength division multiplexing (WDM). These results suggest that the boro-tellurite glass may have potential use in photonic devices designed for near-infrared applications, including optical communication systems.
