Structural Investigations of Cr3+ Ions Doped Alkali Lead Zinc Phosphate Glasses

Abstract

Lead zinc phosphate glasses containing 0.1% transition metal ion Cr 3+ were prepared by melt quenching technique and their amorphous nature confirmed by X-Ray diffraction. The covalent bond nature of Cr 3+ ions with octahedral symmetry in glass network was established through Electron Paramagnetic Resonance and optical absorption spectroscopic studies. Endothermic dip for glass transition temperature (T g ) at about 410 0 C and an exothermic peak subsisted from thermal studies were obtained. De-polymerization of host glass network due to addition of alkali content to the glass matrix, has turned as a strong candidate for nonlinear optical laser applications.
