Resumo: | Europium-doped zinc aluminate (ZnAl2O4:Eu3+) films were prepared by the dip-coating technique using a non-alkoxide precursor sol-gel method in ethanolic medium. Photoluminescence spectra displayed the main excitation bands at 270 and 393 nm. The emission spectra of the film heated at 500 ºC displayed bands at 578, 590, 612, 650 and 698 nm, assigned to the 5D0 → 7F J (J = 0, 1, 2, 3, 4) transitions. The films are transparent above 320 nm. |
