Abstract | Photoluminescence characterization of LiZnVO4 oxides by the vibrating milled solid-state reaction was investigated in this work. The products were characterized by X-ray diffraction, scanning electron microscopy, photoluminescence spectroscopy and absorption spectra. The excitation wavelengths associated with charge transfer bands of [VO4]3− are located at 355 nm. The photoluminescence results reveal that the sample prepared at 500 °C exhibits a broad and strong bluish green emission peaks at about 526 nm compared with other samples. Furthermore, the visible light absorption edge of the LiZnVO4 annealed at 500 °C was located at 413 nm, which corresponded to band-gap energy of 3.0 eV. |
