Eu doped ZnO/SnO2 nanocomposite powder samples with different Eu3+ concentration (0.05–1.00wt%), were synthesized by low temperature co-precipitation method. Powder X-ray diffraction pattern confirmed the presence of both hexagonal ZnO and tetragonal SnO2 simultaneously. The crystallite size was estimated, using Debye Scherrer's method and Hall–Williamson method and it was found to be in the range...
