Abstract Glasses of the system (90-x) P2O5–x PbO– 10Fe2O3 (where 25 B x B 45) mol % were prepared by utilizing meltdown quenching technique. Optical and FTIR spectroscopic measurements are utilized to investigate and characterize the given compositions of lead–iron phosphate glasses. During this work, it is aimed to check the chance of utilizing the prepared glass as a good shielding material for radiation. So as to estimate gamma-ray shielding properties of glass samples, mass attenuation coefficients have calculated with the XCOM computer program. The values of half-value layers are calculated. The changes within FTIR spectra because of the presence of metal oxides were referred to the various housing positions and physical properties of various Fe2? and Pb2? ions. Calculations of optical band gap energies from the ultraviolet light information were given to examine the chance of utilizing these glasses as gamma radiation shielding material. The results of each optical and FTIR spectra of the studied glasses showed that the dual role of Pb2? and Fe 3? ions as glass modifier and former, therefore, the glass is denser and a lot of compacts, therefore reducing its molar volume and increasing its hardness, that confirms

Introduction Phosphate glasses belong to traditional glass materials that may be prepared at low temperatures with a wide range of composition [1]. Phosphate glasses have special properties that make them helpful for a wide range of technical applications like low melting temperature, low crystallization capability, high dielectric constant, high thermal stability and sensible transmission for infrared emission with a wide range of long wavelengths [1–3]. However, these glasses have a comparatively weak chemical durability [1, 2] which frequently reduces its utility because of absorbent nature and therefore the weak chemical strength of phosphate glasses [2]. Several studies and researches [5] showed that the chemical durability of phosphate glasses is often improved by adding totally different oxides like PbO and, particularly, Fe2O3 [2, 5]. As a result, lead–iron phosphate glasses are currently the
