“…For instance, barium, a non-toxic, non-bio accumulative heavy metal, may be added to improve the glass's refractive index and luster [6]. In addition, CdO, as an HMO in glass materials, has a prominent function for various purposes, including solar and fuel cells, electrodes, sensors, K etc [5,[7][8][9]. The functional significance of CdO stems from its many desirable characteristics, including its high atomic number, density, polarizability, transparency, transmission in the Vis and IR regions, thermal stability, and low electrical resistivity, besides its optical nonlinearity and unique covalent nature [7,8].…”

In this work, the structure, elasticity parameters, and buildup factor of borosilicate glasses doped with BaO, CdO and NiO have been studied. Infrared (IR) spectroscopy was utilized to study the internal structure of the present system. IR spectra are broad, especially since the superposition between the borate and silicate occurs in the same spectral region. A deconvolution process was carried out to extract these spectra into their individual bands. The N4 values were found to barely increase from 37.9 % for 1 mol% of NiO reaching 39.5 % for 4 mol% of NiO. A such increase indicates the transformation of BO3 to BO4 units with further additions of NiO. The N4 values were used along with the dissociation energies density and packing density parameters to calculate the elastic moduli; Young, shear, bulk, and Poisson ratio. The obtained values of Young’s modulus increase with further NiO additions. This increased behavior of Young’s modulus demonstrates the augmented ability of the current glasses to withstand variations in their length under lengthwise tensile tension or compression with further NiO additions. The rest of the elasticity moduli showed increased behaviors as well. These increased behaviors support the results obtained from structural properties analyses. An increment of BO4 units with decreasing the nonbridging oxygens (NBO) in the internal structure of present glasses produces an increase in the elastic parameters of these glasses. At photons energy of 0.2 MeV, the values of energy exposure buildup factor (EBF) are low for glasses that have a high concentration of CdO (low concentration of NiO), but the value of EBF is larger for glasses that have a low concentration of CdO (high concentration of NiO).

Transparent conducting oxides, such as doped indium oxide, zinc oxide, and cadmium oxide (CdO), have recently attracted attention as tailorable materials for applications in nanophotonic and plasmonic devices such as low‐loss modulators and all‐optical switches due to their tunable optical properties, fast optical response, and low losses. In this work, optically induced extraordinarily large reflection changes (up to 135%) are demonstrated in bulk CdO films in the mid‐infrared wavelength range close to the epsilon near zero (ENZ) point. To develop a better understanding of how doping level affects the static and dynamic optical properties of CdO, the evolution of the optical properties with yttrium (Y) doping is investigated. An increase in the metallicity and a blueshift of the ENZ point with increasing Y‐concentrations is observed. Broadband all‐optical switching from near‐infrared to mid‐infrared wavelengths is demonstrated. The major photoexcited carrier relaxation mechanisms in CdO are identified and it is shown that the relaxation times can be significantly reduced by increasing the dopant concentration in the film. This work could pave the way to practical dynamic and passive optical and plasmonic devices with doped CdO spanning wavelengths from the ultraviolet to the mid‐infrared region.
