The evolution of economically viable and high-performing nanocrystals (NCs) may result in the creation of more efficient and adaptable optoelectronic devices, hence contributing to technical progress and economic advantages. The (PVA–PEG–SiO<sub>2</sub>/CuO) nanocomposites have been produced using a casting method. Optical microscopy has allowed us to observe that the (SiO<sub>2</sub>/CuO) NMs create a connected network within the NCs, in contrast to the pure (PVA–PEG). The FTIR ray displays changes in the position of peaks and variations in shape and size. The findings of the optical characteristics indicate a significant increase in absorption by approximately 2275% at a wavelength of 550 nm. Additionally, the energy gap experienced a decrease of roughly 57% (from 4.37 to 2.80 eV) for allowed indirect transitions and 120% (from 1.68 to 3.69 eV) for forbidden indirect transitions. An experimental and theoretical investigation explored the optical characteristics of (PVA–PEG–SiO<sub>2</sub>/CuO) NCs. As the concentration of (SiO<sub>2</sub>/CuO) nanoparticles rose, several optical characteristics of the pure (PVA–PEG) material demonstrated an upward trend. Based on the electrical properties of alternating current, it can be observed that as the frequency (f) increases, the dielectric [constant (ε′) and loss (ε″)] of NCs diminish. However, these values increase as nanomaterials (NMs) concentration increases. The ε′ and σ<sub>a.c</sub> (electrical conductivity) of the (PVA–PEG) increased by approximately 101% (from 0.60 to 1.20) and 173% (from 1.25 × 10<sup>–11</sup> to 3.41 × 10<sup>–11</sup>), respectively, when the amount of (SiO<sub>2</sub>/CuO) reached 6% by weight at a frequency of 100 Hz.

The studied halides are structurally and thermodynamically stable in the cubic phase, as shown by the computed Goldschmidt’s tolerance factor and formation energy.

Furthermore, we computed bandgaps with and without spin orbit coupling (SOC) using electrical properties. To obtain corrected bandgap values with respect to experimental data, we used modified Becke–Johnson potentials to compute the bandgap values of K<sub>2</sub>ScAuI<sub>6</sub>(E<sub>g</sub> = 1.92 eV) and K<sub>2</sub>YAuI<sub>6</sub> (E<sub>g</sub> = 1.98 eV).
