“…Lots of research has been carried out on borosilicate glasses due to their wide applications as electrodes, sealants, planar optical wave-guides, optical lenses and glass fibers [1][2][3][4]. As compared to the borosilicate glasses, the phosphate glasses remain amorphous even after accommodating higher concentrations of transition ions [5].…”

The present investigation is an attempt to address the effect of P 2 O 5 on the optical properties, cross link density (n c ) as well as theoretical parameters like Poisson's ratio and bulk modulus for (25-x)%CaO-x%P 2 O 5 -60%SiO 2 -5%B 2 O 3 -10%ZnO (x = 5, 10, 15, 20) novel sol-gel glasses. The optical basicity, oxide polarisability, direct/indirect band gaps and theoretical elastic constants have been calculated for all the glasses. In addition to this, the cross-link density, average force stretching constant and number of network bonds per unit volume (n b ) have been calculated. The values of optical basicity and polarisabilty have allowed the same trend for all these glasses. The cross-link density decreases when the P 2 O 5 content increases from 5 to 20 %.

“…But most of doped Cu 2+ ions easily precipitate on glass surface as Cu metal by reduced heat treatment. 48) In the growth of LN single crystals, the preferred growth directions are a and c directions. In the writing of β -BBO and Ba2TiX2O8 (X = Ge and Si) by laser irradiations, we obtained only c-axis grown lines.…”

“…These can be elucidated using X-ray absorption spectroscopy. The copper species in the glass matrix are varied from Cu, Cu(I) and Cu(II) depending on the glass composition [4][5][6] and condition for preparing glass (oxidative or reductive process) [7][8][9].…”

The silicate glass was prepared using rice husk as the source of silica. The base composition of glass sample was 46SiO2 (from rice husk ash)-19Na2CO3-18H3BO3-13ZnO-3CaO-0.9Al2O3-0.2Sb2O3 mol %. Doping with copper oxide yielded the colored silicate glass. The expansion coefficients of the copper doped glass was 10.76 x 10-6 K-1. The finger prints of the bond vibrations were studied using IR spectroscopy. While the oxidation state and the coordination information of the copper ion in the glass matrix were investigated using X-ray absorption spectroscopy. From the data, Cu+ and Cu2+ exist in the glass matrix.
