摘要：

A series of (75-x) B2O3-xBi(2)O(3)-10Na(2)O-10CaO-5Al(2)O(3) glasses, (0 <= x <= 25 mol%) were prepared. Density and molar volume were measured. FTIR and UV spectra were recorded at 400-4000 cm(-1) and 200-850 nm, respectively. Optical energy gap (E-OPt), Urbach's energy (E-u), and refractive index (n) were calculated using absorption spectrum fitting (ASF) and derivation of absorption spectrum fitting (DASF) methods. Molar refraction (R-m) and molecular polarizability (alpha(m)) have been calculated according to (ASF) method. (C) 2017 Elsevier Ltd. All rights reserved.
