The Spectroscopic Analysis of Iron-Doped Soda-Lime-Silica Glass by Spectrophotometer and ESR Spectrometer
In this work, soda-lime-silica glass has been selected for coloring as base glass. The glass composition in mol% is (65-x) SiO2: 25Na2O: 10CaO: x Fe2O3, where x is 0.00, 0.02, 0.05, 0.10, 0.30, and 0.50. Optical absorption and electrons spin resonance spectroscopy were conducted for five different doping rates. The optical spectra of Fe2O3 doped glasses show three absorption bands at 380, 420 and 435 nm. These peaks correspond to Fe3+ ions. The ESR spectra of all glasses doped with Fe2O3, they show three strong ESR absorption peaks at the g = 2.0050.003, 4.2910.008 and 7.1240.008. The intensity of these peaks is increased when the Fe2O3 concentration is increased.
