摘要：
Cadmium sulphate nanotubes/rods have been synthesized by hydrothermal treatment using CdSO4 powder as precursor and hexadecylamine (HDA) as surfactant at 180 degrees C for 7 days. The powder X-ray diffraction (PXRD) pattern reveals that the CdSO4 nanortubes/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.
