| Popis: | In this paper, we report large-scale high-quality SrWO4 3D microspheres synthesized in aqueous solutions under mild conditions with cetyl trimethyl ammonium bromide as a simple cationic surfactant. These crystals have been characterized by X-ray diffraction, transmission electron microscopy and field emission scanning electron microscopy techniques. The crystal growth processes were employed to investigate the formation mechanism of SrWO4 3D microspheres. Room-temperature photoluminescence indicated that the as-prepared SrWO4 3D microcrystals had strong emission peaks at about 432 and 505 nm, respectively. |
