N2 - Various concentrations of samarium (Sm3+) ion-activated oxyfluoroborate (ANCB:AlF3-NaF-CaF2-B2O3) glasses are fabricated for its applications in red-emitting lasers and scintillators. From the optical absorption spectrum, Ω2,4,6 intensity parameters and several radiative parameters along with the high value of absorption (2.96 × 10−21 cm2) and emission (14.13 × 10−22 cm2) cross sections are calculated. By stimulating at 403 nm, a transition corresponding to 4G5/2 → 6H7/2 (596 nm) is very intense and emits orange-reddish luminescence of Sm3+ ion in ANCB glasses. The decay curves are fit to the Inokuti–Hirayama (I–H) model to determine the energy transfer in Sm3+: ANCB glasses. The X-ray-excited luminescence (XEL) spectra are determined with an X-ray source by supplying the voltage of 50 kV and current 30 mA. The lasing parameters like stimulated emission cross section (14.13 × 10−22 cm2), optical gain (30.52 × 10−22 cm2s), and quantum efficiency (80%) are found to be high for the 4G5/2 → 6H9/2 transition of Sm3+ ions. The quality of the emitted red light for the ANCBSm0.5 glass is calculated in terms of the (x, y) color coordinates and correlated color temperatures (CCT < 3000 K). The integral scintillation efficiency of glasses shows the maximum value of 23% in comparison with Bi4Ge3O12 scintillation crystal.
