Abstract: “The present work provides a potentially efficient and a simple chemical route for the synthesis of CdS & Cd(1-x) MnxS nanocrystals in organic phase at ambient room temperature. The nanostructures of the prepared undoped CdS and Mn2+ doped CdS:Mn nanoparticles have been analysed using UV-vis spectrophotometer, Fourier Transform Infrared studies and fluorescence emission spectra have been studied. There is a wavelength shift in the emission of manganese doped samples. The size and shape of the synthesized nanoparticles have been studied using the Transmission Electron Microscope.Chemical manipulation towards both size and shape tunable preparation is achieved successfully.”
