摘要：Lead zinc phosphate glasses containing 0.1% transition metal ion Cr3+ were prepared by melt quenchingtechnique and their amorphous nature confirmed by X-Ray diffraction. The covalent bond nature of Cr3+ ions withoctahedral symmetry in glass network was established through Electron Paramagnetic Resonance and opticalabsorption spectroscopic studies. Endothermic dip for glass transition temperature (Tg) at about 410 0C and anexothermic peak subsisted from thermal studies were obtained. De-polymerization of host glass network due toaddition of alkali content to the glass matrix, has turned as a strong candidate for nonlinear optical laser applications.
