What is Evaluation of the structural, optical, and γ-attenuation properties of Holmium Dolomite Glass for high-transmittance optical devices about?
In this study, the structural and optical properties as well as the radiation shielding capabilities of Holmium Dolomite Glass (HDG) 30CaMgC 2 O 6 -34P 2 O 5 -(36-x)CdO-(xHo 2 O 3 ), (x = 0, 1, 2, 3, and 5 wt%), were investigated. The HDG samples were prepared using a melt-quenching method, and X-ray diffraction (XRD) analysis revealed that they had an amorphous structure with no prominent peaks. The FTIR spectra over a range from 4000 to 400 cm− 1 and a deconvoluted view of the spectra within the 1600-400 cm− 1 range were recorded. The optical properties were characterized through transmission and reflectance spectra across a wide wavelength range. HDG exhibited high optical transmission, with over 90 % average transmittance in the visible spectrum. The refractive index was found to be in the range of 2.1-2.3, while the absorption coefficient exhibited values between 0.01 and 0.1 across the studied wavelengths. The calculated direct energy gap E Opt g value for HDG is 4.43 eV which decreased to 3.91 eV upon increasing Holmium concentrations in HDG. Beyond optical properties, we delved into the radiation shielding capabilities of the HDG samples by meticulously measuring linear att
