- Abstract
One-dimensional (1 D) Co-doped CdTe nanorods (NRs) and nanochain assemblies were prepared by spontaneous self-organization of Co-doped CdTe nanoparticles (NPs) in an aqueous solution. The effect of different growth conditions on the formation of 1 D assemblies was studied. Formation of nanochains was accelerated by the addition of 50% dimethylsulfoxide to the aqueous growth solution. NRs were obtained by keeping the growth solution at low temperature (4 °C) for 4 days, followed by room-temperature aging for another 4 days. X-ray diffraction patterns of the Co-doped CdTe NPs showed that the same crystal structure as the CdTe nanocrystals was retained, indicating no second phase formation for the Co ions. XPS and ICP-AES data demonstrated successful incorporation of Co ion within CdTe NPs. The room-temperature susceptibility values of Co-doped NPs increased with the doping percentage of Co ions.
