FTIR and NIR spectroscopic analyses of Co3O4-doped sodium zinc borate glass matrix

In this paper, the samples of network of borate glass have been prepared by melt quenching technique and characterized. Optical characterization of the network was examined By UV-VIS spectroscopic technique. The results showed an increasing in refractive index, permittivity, extinction coefficient, dielectric constants, electric susceptibility and polarizability with increasing Co3O4 content. Cobalt ions produced intense blue color in glass and used as optical filters in UV-VIS region. Fourier-transform infrared spectroscopy is used to characterize the local order and kind of forming structural units and provides information about the interaction between alkali metal ions and borate glass network. Addition modified oxide of cobalt oxide converts some of BO3 to BO4 units. Glass samples are exposed to melting and grinded so the resulted bands are very broadening and overlapping to analyze this overlap used deconvolution analysis technique. Cobalt-doped borate glass behaved as optical band pass filters, i.e., area, center, width and height of band pass.
