Synthesis and characterization of CePO_4 nanowires via microemulsion method at room temperature

摘要

Uniform CePO_4 nanowires with diameter of about 25 nm were synthesized by the water-in-oil microemulsion method at room temperature from cerous chloride,sodium orthophosphate,sodium chloride,cyclohexane,Triton X-100 and cetyltrimethyl ammonium bromide(CTAB).The crystal structure and morphology of the nanowires were characterized by XRD and TEM, respectively.The UV-vis absorption was detected by UV-vis spectrophotometer techniques.The results showed that as-prepared nanowires with the hexagonal phase have obvious quantum confinement effect and semiconductor characteristics.Little sodium chloride could play a positive role on the formation of CePO_4 nanowires at room temperature.The size of the nanowires can be controlled through the joining of sodium chloride.
