Abstract
Within the scope of the study, glasses co-doped with Sm3+/Gd3+ based on the B2O3–GeO2–Bi2O3 system were synthesized, covering compositions of 40B2O3–40GeO2–(15 – 17)Bi2O3–(3 – 2)Sm2O3–(2 – 1)Gd2O3 and 42.5B2O3–42.5GeO2–(11.25 – 12.75)Bi2O3–(2.25 – 1.50)Sm2O3–(1.500 – 0.075)Gd2O3. An assessment of luminescent characteristics was carried out within the temperature range of 298 – 673 K. Spectral bands of photoluminescence associated with transitions between various Stark sublevels of Sm3+ ions were identified. Redistribution of the fluorescence intensity ratio corresponding to 4G5/2 → 6H9/2 (\({\uplambda }_{\mathrm{PL}}^{\mathrm{max}}\) = 645 nm) and 4G5/2 → 6H7/2 (\({\uplambda }_{\mathrm{PL}}^{\mathrm{max}}\) = 597 nm) transitions was observed. Based on the obtained data, calculations of the fluorescence intensity ratio FIR, as well as relative sensitivity SR, were carried out. The obtained results indicate the promising potential of these glasses as luminescent thermometric materials.
