Investigation of the spectral characteristics of Sm³⁺ ions in lead borosilicate glass for photonic applications

Abstract

Different concentrations of Sm2O3 doped lead borosilicate glasses were synthesized by using the method melt quenching and their characteristics were analyze using X‐ray diffraction (XRD), Fourier transform infrared (FTIR), absorption, emission, and decay curves. From the XRD, it has been confirmed the non‐crystalline nature of titled glasses. The structural groups that were existing in the host glass have been discovered by looking at the FTIR spectrum. The Judd‐Ofelt (JO) intensity parameters and oscillator strengths are derived from the absorption spectra and compared to with various reported systems. The excited luminescent levels of the Sm3+ ion's radiative properties are further computed using the JO intensity parameters. Effective bandwidth, emission cross‐sections (σe), and several lasing properties are assessed from emission spectra and compared to other reported glass system. The decay curves of 4G5/2 level of Sm3+ ion has also been measured and examined. Additionally, the color coordinates of the CIE (Commission International de I'Eclairage) chromaticity were assessed. The titled glasses were suited for visible reddish‐orange luminescence devices based on all obtained parameters.
