Abstract
Glasses in the system 20Na2O-Al2O3- 13B2O3-6.3CaO-0.2Sb2O3-1.5PbO 2-(58-x)SiO2-xCuO were prepared with x = 0.0, 0.2, 0.4, 0.6 and 0.8 mol% respectively. ESR absorption spectra due to Cu2+ (3d9) ions show that the ESR signal at 0.2 and 0.4 mol%CuO were similarity, the perpendicular g-value, gx. can be observed at 2.06 whereas the parallel g-value, g// cannot be observed. The line width of board line centers were depends on the increasing of concentration of CuO-doped. CuO-doped glasses give rise light blue green color. Confirm from optical absorption techniques as UV-VIS measurment reported were recorded at room temperature. The absorption band near 800 nm (2B1g→ 2B2g) is due to Jahn-Teller effect of Cu2+. Also absorption band at around 400 nm (2B1g→ 2Eg) could be found due to d-d transition of Cu 2+ ion in the CuO doped glasses. The results obtained suggest that Cu ions substitutes as an accepted center for [SiO2]4+ in oxygen octahedral rhombohedral distortion. © 2008 Trans Tech Publications, Switzerland.
