ABSTRACT: Glasses samples containing Ho3+ in Ytterium Zinc Lithium Sodalime Magnesium Phosphate Glasses (45-x)P2O5: 10ZnO: 10Li2O: 10Na2O: 15CaO: 10MgO: 10Y2O3 :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. DTA curve was analysed to evaluate the glass transition temperature, crystallization temperature and melting temperature Optical absorption, Excitation and fluorescence spectra were recorded at room temperature....
