In the present paper, we report the successful synthesis of spinel-type of CuCrO and La doped CuCrO semiconductor nanoparticles by a microwave method. Starting with the precursor complex, this technique includes the creation of homogenous solid intermediates, which reduces atomic diffusion pathways during the microwave process. CuCrO and La doped CuCrO were characterized by the following analytical methods for instance X-ray diffraction (XRD), transmission electron microscopy (TEM), Ultraviolet-visible (UV-Vis) spectroscopy and Fourier transform infrared spectroscopy (FTIR). The results demonstrated that modifying the precursor had a significant impact on the size, solar cell size, as well as reaction period of synthesizing CuCrO and La doped CuCrO. The impacts of precursors on the morphological and structural characteristics of CuCrO and La doped CuCrO were examined for the first time in this publication.

For applications involving LED lighting and displays, phosphor materials with narrow emission bands are quite riveting. CuCrO is a well-known delafosste for optoelectronic device applications due to its wide bandgap, and high emission at short wavelengths. Here we tried emission band tuning of CuCrO by Ni on 0.

Semiconductor metal oxide with TiO nanoparticles removes hazardous compounds from environmental samples. TiO nanoparticles have shown potential as an efficient photocatalyst by being employed as a nano-catalyst for the breakdown of organic contaminants in wastewater samples. To separate substances from contaminated samples, combined UV and visible light irradiation has been used.

We propose and fabricate a heterojunction between Al-doped ZnO and (Mg, N)-doped CuCrO thin films using the sputtering deposition method. These materials possess wide bandgap that makes them transparent in the visible light but excellent UV-absorbers. On the other hand, the high conductivity of these materials, respectively as n-type and p-type transparent conducting oxides, facilitates the charge transport.

Off-stoichiometric copper chromium delafossites demonstrate the highest values of electric conductivity among the p-type transparent conducting oxides. Morphological and structural changes in CuCrO upon annealing processes are investigated. Chained copper vacancies were previously suggested as source of the high levels of doping in this material.
