Molecular spectroscopic analysis of cobalt oxide-doped copper zinc sodium phosphate glass matrix

摘要

Abstract A glass system of 40P2O5–(21???x) Na2O–38ZnO–x Co3O4–1CuO where (x?=?1, 2, 3, 4 and 5) has been prepared by melt quenching technique. The density of the glasses was measured, and molar volume was calculated. The structure has been investigated using IR spectroscopy. The spectral analyses showed that the addition of Co3O4 to P2O5 glass is unequivocally influencing the short-range order of the glassy matrix. The spectra also denote the formation of P–O–Co bonds in the glasses that replace P–O?–Na+ bonds. The results are related to the dual role of cobalt ions as a glass former and modifier.
