Abstract :Copper oxide nanoparticles (CuO NPs) were synthesized at 105 °C via a hydrothermal deposition technique. The CuO nanoparticle structure was characterized via X-ray diffraction (XRD) and scanning electron microscopy (SEM). The optical properties of the nanoparticles were examined via a UV‒vis spectrophotometer. For all the nanoparticles, the XRD measurements revealed the monoclinic CuO phase. The direct optical band and Urbach gap width of the nanoparticles were 2.88 eV and 0.44 eV, respectively. On the basis of optical measurements, optical parameters such as the refractive index (n), extinction coefficient (k), and real (ε1) and imaginary (ε2) components of the dielectric constant were calculated. At a wavelength of 550 nm, the optical constants n and k were found to be 2.75 and 0.00024, respectively, corresponding to dielectric real and imaginary constants of 7.570 and 0.0013. Additionally, photon interactions with CuO NPs at various energy levels were simulated via the FLUKA program. The energy deposition in the material provided valuable information for assessing the radiation shielding capabilities of the investigated material.
