Eu-doped ZnO (ZnO:Eu<sup>3+</sup>) thin films deposited by RF magnetron sputtering have been investigated to establish the effect of annealing on the red photoluminescence. PL spectra analysis reveal a correlation between the characteristics of the red photoluminescence and the annealing temperature, suggesting efficient energy transfer from the ZnO host to the Eu<sup>3+</sup> ions as enhanced by the intrinsic defects levels. Five peaks corresponding to <sup>5</sup>D0-7F<sub>J</sub> transitions ...[more]
