Effect of ion implantation on physical, optical properties and gamma-ray shielding capacity of boro-zinc bismuthate glasses

The present study examined the effect of nitrogen ion implantation on the physical and optical properties of prepared glasses. Implantation of N + ions was performed at concentrations of 5 × 10 16 and 5 × 10 17 ions/cm 2 and energy of 150 keV. The morphological investigation was conducted using SEM analysis. The structural change is primarily comprehended through optical and physical investigation. With increasing ion concentrations, the optical band gap shifts and the cut-off wavelength increases simultaneously. This is due to the band edge sharpness induced by band tailing introduced during the implantation procedure. In addition, measurements of the glass transition temperatures revealed that as ion concentrations increased, the glass structure became less rigid. These results shed light on the effects of nitrogen ion implantation on the numerous properties of glasses. Results revealed that the sample encoded as Bi-10 possessed the highest values of mass and linear attenuation coefficients among all studied glasses. In terms of the half, tenth value layers, and mean free path, the sample Bi-10 possessed the lowest values. Therefore, the Bi-10 sample had the highest capacity as radiation shielding glasses.
