The study demonstrates how dy3+ doped borosilicate glasses improve thermal stability, suggesting valuable radiative properties.
Glass sample of yttrerbium zinc lithium sodalimealumino borosilicate(25- x)SiO2:10ZnO:10Li2O:10Na2O:10K2O:10Al2O3:10Yb2O3:15B2O3:xDy2O3.(wherex=1,1.5 and 2 mol%) have been prepared by melt-quenching technique. The amorphous nature of the prepared glasssamples was confirmed by X-ray diffraction. Optical absorption,excitation spectrum, fluorescence and raman spectra were recorded at roomtemperature for all glass samples.Judd-Ofeltintensity parameters Ωλ (λ=2, 4 and6) are evaluated from theintensities of various absorption bands of opticalabsorption spectra. Using these intensity parameters variousradiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulatedemission cross–section of various emission lines have been evaluated
