\(Gd^{3+}\) / \(Sm^{3+}\) Co-doped Lead Alumino-borophosphate Glasses: Synthesis and Characterization | Chapter 5 | Chemical and Materials Sciences: Research Findings Vol. 4

 

A series of multicomponent (Lead, Sodium, Aluminum and Zinc) Borophosphate glasses doped with Sm3+ and Gd3+ ions with molar composition xPbO - (40-0.5x)B2O3 - (40-0.5x)P2O5 - 9.0Na2O - 1.0Al2O3 - 9.6ZnO - 0.2Sm2O3 - 0.2Gd2O3 (x = 10, 15, 20, 25, 30, 35) was synthesized using the conventional melt quenching technique. The amorphous nature of these glasses was confirmed with XRD studies. The density measurement was done by using Archimedes' principle with the help of a KEROY mechanical balance. The density measurements show a regular and systematic increase in density from 3.6008 g/cm3 to 4.6397 g/cm3 with an increase in PbO content in exchange for the two glass formers. The optical absorption spectra of these glasses were recorded by using a UV/visible spectrometer (Shimadzu, Japan) in the wavelength range of 200–1100 nm at normal incidence. The values of Eg for the glass samples of the series decrease with an increase in PbO content. The synthesised samples may find applications for energy converters, X-ray dosimeters, and radiation shielders/sensors.
