Oxide based dilute magnetic semiconductor materials are of great interest and this study focusses on the optical behavior non-magnetic element doped TiO<sub>2</sub> nanocrystals which provides a significant reduction in bandgap with enhanced magnetization.
The magnetic behavior of TiO2 and doped nanocrystals has been a challenge due to the unambiguous nature defects present in oxide semiconductors. Here, simple, low-temperature sol–gel method is developed for synthesis low-dimensional highly efficient stable anatase nanocrystals. X-ray powder diffraction pattern Raman spectra confirm formation single-phase structure TiO2. High-resolution transmission electron microscopy studies reveal crystalline sol–gel-derived increase lattice parameters...

Dilute magnetic oxide semiconductors doped with transition metals have attracted significant attention both theoretically and experimentally due to their interesting debatable behavior. In this work, we investigated the influence of Fe, Co Ni doping on structural, optical properties SnO
The growth mechanism of the CuO single-crystal nanowires (NWs) for future device applications has been demonstrated using copper films deposited on CuO-buffered substrates. involves a two-step process: In first step, hillocks are formed to relieve compressive stress existing at high temperature long duration time in air and then phase is by oxidation ambient. second step continuous supply through porous seed transformation NW. NW was grown both from oxygen air. indispensable requirements presence
Graphene and semiconductor nanocomposite garnered much interest in nanoscience nanotechnology. In this research, TiO 2 , : Sr Sr/r-GO (reduced graphene oxide) nanocomposites have been successfully synthesized via a wet chemical synthesis method.
