Synthesis and characterization of CdIn2S4 nanorods by converting CdS nanorods via the hydrothermal route

The ternary semiconductor CdIn2S4 nanorods were synthesized by a method bas ed on CdS nanorods via the hydrothermal route, in which CdS nanorods were c onverted by reaction with InCl3 and thiourea in aqueous-solution Transmissi on electronmicroscopy (TEM) images revealed that the typical sizes of the C dIn2S4 nanorods were 10-30 nm in diameter and 200-1000 nm in length. X-ray photoelectron spectra (XPS) analysis of the surface stoichiometry (CdIn2.03 S4.15) and room-temperature Raman spectrum (RS) were recorded. The influenc es of reaction temperature, time, and sulfur sources on the formation for C dIn2S4 nanorods were investigated. A possible formation mechanism of the Cd In2S4 nanorods was also proposed.
