Comprehensive study on optical and luminescence properties of Sm3+ doped magnesium borotellurite glasses

Structural, photoluminescence, and optical characteristics of a Sm3+‐doped lead borate–strontium–tungsten glass system: Evaluation of Judd–Ofelt intensity parameters and radiative properties

“…With the gradual introduction of samarium ions into the base glass sample, noticeable bands were observed. In Figure 2a the only observed band was detected at approximately 475 nm that corresponded to the overlapped transitions from the ground state 6 H 5/2 to 4 G 9/2 , 4 I 11/2 , and 4 F 5/2 excited energy states [1, 13, 33, 34].…”

“…Lately, rare earth (RE)‐doped glass have gained significant consideration and are used in vast commercial applications. They are employed to develop advanced lasers and optical devices [13–18] due to their unique photoluminescence properties [1, 19–21]. They are commonly utilized to investigate the structural changes in a glass host due to their distinctive properties emanating from the optical transitions in their unfilled 4 f shell [22].…”

“…Amongst several glass‐forming oxides [1–4], boric acid (B 2 O 3 ) is the most abundantly used due to its small B 3+ ion size and strong covalent B–O bond strength. Borate‐based glass are considered to have the highest glass formation tendency [5].…”

“…Moreover, the band shapes and positions were not affected by varying the Sm 2 O 3 contents. Furthermore, the observed transitions from the ground state 6 H 5/2 to the manifold 6 F and 6 H levels are more intense in comparison with 4 F and 4 G transitions; Zalamin et al argued that the high intensity is due to the spin-allowed selection rule (ΔS = 0) [ 54 ]. However, the introduction of copper oxide nanoparticles reasonably enhanced the absorbance of the glass samples, as evidenced by the absorption spectra.…”
