Fabrication of Luminescent Cadmium Sulfide Nanofibres in Inverse Microemulsion via PEG-400 as the Template by g-Irradiation

Abstract

Luminescent cadmium sulfide nanofibres with average diameters of 100 nm and lengths up to 3 μm were successfully prepared in large scale in inverse microemulsion under g-irradiation and the addition of polyethylene glycol-400 (PEG-400) as the template at room temperature and under ambient pressure, which was confirmed by the observation of transmission electron microscopy, field-emission scanning electron microscopy and X-ray powder diffraction. Additionally, the chemical composition of cadmium sulfide nanofibres was determined with X-ray photoelectron spectroscopy and the optical properties of cadmium sulfide nanofibres were characterized by ultraviolet-visible and photoluminescence spectroscopies.
