Investigation of radiation shielding and optical properties of neodymium doped Bismuth Boro tellurite glasses for solid state device applications

Abstract

In this work, a variety of glass samples with different chemical profiles for optical applications were synthesized, and characterized. The thermal properties of the prepared glass are investigated through Differential Thermal Analysis (DTA) and we have observed the endothermic peak at 894.9 °C and exothermic peak at 1066 °C. The optical properties were investigated using a UV–Visible–NIR Spectrophotometer, and the radiation shielding properties were reported using the Phy-X/PDS software. The optical property results show that when the amount of Nd3+ ions in a glass structure grows, the oscillator strengths also increase. The high emission cross-section and excellent quantum efficiency indicate that glass has the potential for compact 1.06 μm laser applications. The Photoluminescence (PL) analysis of Nd3+ ions doped prepared glass samples are recorded at 808 nm laser diode. The emission spectra for every Nd3+ ion concentration exhibit three distinct emission peaks at wavelengths of 902 nm, 1064 nm, and 1339 nm. The investigation of luminescence kinetics revealed the development of neodymium ion clusters commencing at a neodymium concentration of 1.006 × 1020cm−3. Furthermore, we noticed that the addition of Nd2O3 increased the mass attenuation coefficient and effective atomic number of the glass samples. In terms of the glasses' ability to absorb charged particles, the Nd2O3 addition also made a difference in Half Value Layer, Mean Free Path, and Effective atomic number. The research shows that the glass samples are non-toxic, visible light transparent, and radiation-efficient.
