SOLVOTHERMAL SYNTHESIS AND OPTICAL PROPERTIES OF WURTZITE-TYPE CdS NANORODS
نویسندگان
چکیده
Cadmium sulfide (CdS) nanorods were synthesized by simple solvothermal reactions at 200 C for 12-24 h using Cd(NO3)2·4H2O and NH2CSNH2 as starting materials and (C2H5)2NH as solvent. XRD and TEM analysis show a hexagonal-phase single crystalline CdS nanorods with diameter of 20 nm and length of 100-200 μm. UV-visible absorption of as-prepared CdS nanorods presented an absorption peak of around 482 nm. The PL spectrum exhibited an emission band at 403 nm due to electron–hole recombination of CdS.

In this study, sea-urchin shaped Bi2S3/CdS hierarchical heterostructures are successfully synthesized via a convenient one-pot growth rate controlled route. The product is mainly composed of Bi2S3 nanorods and CdS nanoparticles grown on their surfaces. The formation mechanism was proposed based on the evolution of morphology as a function of solvothermal time, which involves fast formation of t...

The ZnO-CdS core-shell composite nanorods with CdS shell layer thicknesses of 5 and 20 nm were synthesized by combining the hydrothermal growth of ZnO nanorods with the sputtering thin-film deposition of CdS crystallites. The microstructures and optical properties of the ZnO-CdS nanorods were associated with the CdS shell layer thickness. A thicker CdS shell layer resulted in a rougher surface ...
