| Article Name : | | | EFFECT OF ELECTRON BEAM IRRADIATION ON NANOSTRUCTURED COPPER TELLURIDE THIN FILM | | Author Name : | | | R S Gaikwad , S S Dhasade | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-6068 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | As deposited Copper telluride flower like microstructures constructed by quantum dots with various diameters were obtained by potentiostatic electrodeposition method. The electrolyte concentration and deposition time can be used to control the diameter of the electrodeposited quantum dots to within the range of 50-65 nm. As deposited films are found to be stoichiometric in composition. The thin films are prepared using electrodeposition technique at room temperature and irradiated with electron beam of 2Mev. The surface morphology of film shows drastic change after irradiation. Onion flower like structure with quantum dots changes to coli flower like structure with quantum dots within the range of 20-25 nm. The optical constants such as optical band gap energy and optical absorption spectra shows significant variation in their values with electron beam irradiation. Upon irradiation the band gap energy increased from a value of 2.74eV to 2.88 eV and 2.89 eV to 3.01eV. The structural, optical, surface morphology, compositional analysis and Raman spectra properties of the irradiated films have been studied. | | Keywords : | | |
