| Abstract: | Cadmium sulphate nanotubes/rods have been synthesized by hydrothermal treatment using CdSO4 powder as precursor and hexadecylamine (HDA) as surfactant at 180 °C for 7 days. The powder X-ray diffraction (PXRD) pattern reveals that the CdSO4 nanotubes/rods are of orthorhombic phase. Fourier transform infrared (FTIR) spectrum shows characteristic bands due to the sulfate ion in 1114 cm? 1 and 617 cm? 1 region, besides bands due to the amine moiety. Transmission electron micrograph (TEM) images reveal the nanorods are of 10–15 nm in thickness and nanotubes of wall thickness 5–8 nm. UV–visible absorption spectrum of CdSO4 nanotubes/rods shows the peak at 221 nm. Photoluminescence (PL) spectrum exhibits an intense UV band at 372 nm and weak green band at 484 nm. |
