One dimensional semiconductor nanorods of CdSe were successfully synthesized by solvothermal method using hydrazine hydrate (HH) and ethylenediamine tetraacetic acid (EDTA) as complexing agents. The average diameter of nanorods was found to be around 30 nm and 40 nm from XRD analysis. Thus there is a strong blue-shift in the absorption spectra for both the samples HH and EDTA capped CdSe, indicating that particles must be smaller than the exciton Bohr radius. The emission peak (PL) observed at 560 and 562 nm is attributed to the recombination of charge carriers on the surface of the nanorods.
