On the structure and optical band gap in (Bi2O3)(0.2)(BaO)(x)(B2O3)(0.8-2x)(GeO2)(x) glasses
Original language description
New (Bi2O3)(0.2)(BaO)(x)(B2O3)(0.8-2x)(GeO2)(x) glasses were prepared from pure oxides. The glass transition temperatures decreased from 489 to 460 degrees C with the increase in x from 0.05 to 0.3, simultaneously the coefficient of thermal expansion increased from 7.3 to 9.6 ppm degrees C-1. The optical band gap was determined in the region 3.84 (x = 0.05) - 3.54 eV for x = 0.3, the coefficient of the temperature dependence of the optical gap for the temperatures between 30 and 250 degrees C was foundin the narrow region 3.3 x 10(-4) - 4 x 10(-4) eVK(-1) and the non-linear refractive index of the studied glasses was estimated from the optical gap values at around 6.9 x 10(-11) esu. Possible structural arrangement of the glasses prepared as indicatedby Raman spectroscopy was discussed.
