A nanocube of Ni-doped CsPbBr3nanocrystals (NCs) has been successfully synthesized and characterized by various spectroscopy techniques such as High-resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), etc. The optoelectronic properties of NCs have been investigated with different solvents. HR-TEM and FE-SEM reveal that the obtained Ni-doped CsPbBr3NCs exhibit cubic-rectangular morphologies with different sizes. Furthermore, the radiative exciton kinetics of NCs was examined using the time-correlated single photon counting (TCSPC) technique. The present study ravels that synthesized nanocubes are highly stable.
