Abstract

Glass of the system: (40-x) P2O5:10ZnO:10Li2O:10CdO:10MgO:20B2O3: xDy2O3. (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. (where x=1,1.5 and 2 mol%) have been prepared by melt-quenching technique. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction. Optical absorption, Excitation, fluorescence and FTIR spectra have been 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, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated.

Introduction

Conclusion

In the present study, the glass samples of composition (40-x) P2O5:10ZnO:10Li2O:10CdO:10MgO:20B2O3 : xDy2O3 (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 (4F9/2?6H13/2) for all glass specimens. This shows that (4F9/2?6H13/2) transition is most probable transition. ). The FTIR of glasses revealed the presence of characteristic bonding vibrations of different functional groups.
