摘要：

Eu3+ doped cadmium sulphide (Cd0.98Eu0.2S) nanostructures were synthesised by chemical co-precipitation method using isopropyl alcohol (IPA): DI water and ethylene glycol (EG): DI water as mixed solvents. Powder XRD reveals the formation of hexagonal (wurtzite) and cubic (zinc blende) phase of Eu:CdS with different solvents. From the SEM micrographs the formation of flower and paddy like structures of Eu3+ doped CdS was observed. The stoichiometric chemical composition of the samples was studied using ICP analysis. Band gap values of Eu:CdS nartocrystals synthesized from different solvents were estimated using UV-reflectance spectra. The presence of Eu3+ ion shows significant changes in the PL emission of the CdS nanocrystals. It was observed that the shift in the emission and efficiency of Eu:CdS depends on size and shapes of the synthesised nanoparticles.
