Spectral and Thermal properties of Ho3+ ions doped Zinc LithiumAlumino Potassiumniobate Borophosphate Glasses
Glass of the system: (35-x) P2O5:10ZnO:10Li2O:10Al2O3:10K2O:10Nb2O3:15B2O3: xHo2O3. (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method.The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. Optical absorption, Excitation, fluorescence, and Thermal spectra were recorded at room temperature for all glass samples. Judd-Ofeltintensity parameters Ωλ (λ=2, 4 and6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability (A), branching ratio (β), radiative lifetime(τR) and stimulated emission cross-section( σp)of various emission lines have been evaluated.
