Monte-Carlo Simulation aided design for Preparation of radiation shielding glasses
Abeer Maher Attia Hassan;
Abstract
Optical, structural, and shielding properties of a new inexpensive vitreous system of lithium sodium borosilicate glass containing PbO are studied. The studied glass system was prepared using the conventional melt quenching process and has the form xPbO – 40B2O3–25 Na2O– 5Li2O – (30 - x) SiO2 (where x = 0, 5, 10, 15, 20 and 25mol %).
The amorphous nature and the influence of Pb+2 ions in the glass structure were explored using X-ray diffraction pattern (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) in the range of 4000 – 400 cm-1 respectively. Many groups of bonds such as BO3 and BO4 also the formation of Pb+2 observed in the FTIR spectra. A double beam spectrophotometer was used to record the optical reflectance, R, and the transmittance, T, at room temperature in the spectral range (190-2500 nm). The wavelengths cutoff of the various samples was increased with increasing lead concentration, the direct and indirect transition optical band gaps of these samples decreased from 3.51 eV to 2.82 eV and from 3.28 to 2.45 eV respectively. The refractive index was increased with increasing the lead concentration. Usin
