Abstract

We reported a simple oleylamine-mediated method for preparation of Bi2S3 nanorod materials using BiCl3 and thiourea as reaction precursors. The as-obtained products were characterized by powder X-ray diffraction (XRD), X-ray energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM) and high-resolution TEM (HRTEM). A photodetection device, which was based on a white light source of xenon lamp and a two-probe method using an electrochemical station, was constructed to evaluate the light responsive property of Bi2S3 nanorods. Measurements on current voltage (I V) curves and time-dependent photocurrent response under the white-light on–off states indicated that the as-fabricated Bi2S3 nanorod photodetector showed clearly enhanced photo-currency (photo-conductance), stability and response reproducibility, enabling Bi2S3 nanorods to be a promising material for photodetection, optical switch and other photoelectric devices.
