摘要

Nanocrystals of europium doped tin oxide have been prepared under ultrasonication using the precursors SnCl2·2H2O and Eu(NO3)3·6H2O in the ethanol solvent. The crystalline structure and grain size of Eu doped SnO2 were determined from the powder X-ray diffraction (XRD) pattern. The elemental composition of SnO2:Eu3+ was analysed by Energy Dispersive X-ray (EDX) spectrum. The surface morphology and size of the particles of the synthesized nano semiconductor were discussed through the images taken by Field Emission Scanning Electron Microscope (FESEM) and High Resolution Transmission Electron Microscope (HRTEM). The photoluminescence emissions at 583, 623 and 653 nm were absorbed in the emission spectra due to the dopant Eu3+.
