The size dependent CdTe nanoparticles showed maximum photon absorption blue shift near 375nm wavelength in the UV region ascribed as first excitonic transition as result of reduction of particle radius with increase of band gaps. 5 Mev Figure 4.2: Relation between Transmission of Gamma Rays versus Thickness through. The relationship between the energies of incident and final photon can be. Figure 2.1: The process of photoelectric effect in the atom The. The lattice parameters of the nanocrystals were estimated and observed to be closed agreement with the standard JCPDS data. Compton scattering is the elastic collision between a photon and a free. The particle radius in the films were estimated from the broadening X-ray line profiles of maximum peaks of the spectra which approached the quantum dots (QDs) regime. Apart from the self-Compton process, we take into account Compton scattering of stellar and accretion photons and absorption of very high energy -rays by. The peak intensity is observed enhanced to a maximum value with new (200) plane at Ce 3+ : 10 at.%. %-8 at.% with identical (110) and (111) crystal reflecting planes. The surface structures of the films were studied with FESEM technique and the XRD line profiles of the films revealed with fair growth of nanostructures with decreasing peak intensity with increase of Ce 3+ doses between 2 at. ![]() ![]() CdTe thin films deposited with Ce 3+ at different doping concentration were synthesized by Ionic Layer Adsorption and Reaction (SILAR) technique.
