Spectral and FTIR Analysis of Ho3+ ions doped ZincLithium Potassium Calcium Alumino Borophosphate Glasses

Abstract

Glasses samples containing Ho3+ in zinc lithium potassium calcium alumino borophosphate glasses (30-x)P2O5: 10ZnO: 10Li2O: 10K2O: 10CaO: 10Al2O3:20B2O3: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 FTIR spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters ?? (?=2, 4 and 6) 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 (?), radiative life time (?R) and stimulated emission cross–section ( ?p) of various emission lines have been evaluated.

Introduction

Conclusion

In the present study, the glass samples of composition (30-x)P2O5: 10ZnO: 10Li2O: 10K2O: 10CaO: 10Al2O3:20B2O3:xHo2O3. (where x =1, 1.5and 2mol %) have been prepared by melt-quenching method. The value of stimulated emission cross-section (?p) is found to be maximum for the transition (5I7?5I8) for glass ZLPCABP (HO 01), suggesting that glass ZLPCABP (HO 01) is better compared to the other two glass systems ZLPCABP (HO1.5) and ZLPCABP (HO 02). The large stimulated emission cross section in tellurite glasses suggests the possibility of utilizing these systems as laser materials. The FTIR of glasses revealed the presence of characteristic bonding vibrations of different functional groups
