Surfactant-assisted synthesis and characterization of SrCrO₄ nanostructures

A simple and efficient microemulsion-based technique, which used the new Tx-100/cyclohexanol/ H₂O system, was developed to synthesize SrCrO₄ nanowire based nanostructures, including nanowire bundles and flower-like structures at different temperature. X-ray powder diffraction (XRD), field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) were used to characterize the products. Studies found that the reaction temperatures and the reaction systems have great influences on the final products. Optical properties studies by UV-Vis spectra and photoluminescence (PL) spectra confirmed that the asobtained nanowires showed distinct optical activity under UV and visible light irradiation.
