Summary: | [Display omitted]
•In this work, synthesized graphene-in-cooperation Indium Tin Oxide (ITO) using a high energy ball mill.•UV-DRS was used to characterize the absorption band between 310 and 380 nm.•Surface morphology of the prepared samples was analyzed using FESEM, revealing the polyhedral structure of ITO.•In the PL spectra, we observed a UV emission peak at 374 nm and a blue-green emission peak at 446 nm for ITO, ITO-G (1 %), and ITO-GO (2 %).•Finally, isothermal magnetization was performed for pure and graphene-incorporated ITO.
In this work, we synthesized graphene (g) – incorporated Indium Tin Oxide (ITO) and investigated its structural, morphological, electrical, optical and magnetic properties. The ITO materials, including the 1 % and 2 % g-ITO variants, have a cubic crystal phase, while graphene possesses a hexagonal lattice structure. The Raman spectra exhibited distinct ITO peaks, along with the presence of active modes such as A1, E1, and Eg associated with the CC stretching peak. UV-DRS was performed to study the optical absorption properties in the range of 200–900 nm for the as-prepared ITO, ITO-g (1 %), and ITO-g (2 %) composites. The composite exhibited energy absorption at wavelengths of 320, 314, and 312 nm for ITO, ITO-g (1 %), and ITO-g (2 %), respectively. The photoluminescence spectra exhibited a prominent ultraviolet emission peak at a wavelength of 374 nm as well as a blue-green emission peak at 446 nm, which were found in both the pure and doped samples. Finally, electrical and magnetization was conducted on both unadulterated and g-ITO. |
