Abstract
Abstract Lanthanum aluminate (LaAlO 3 ) nanophosphors doped with erbium were successfully synthesized by a combustion process. The powders were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and fluorescence spectroscopy. Pure LaAlO 3 phase was obtained at 800 °C heated for 4 h, with an average crystal size, as determined by TEM, of 60 nm. Infrared emission spectra and decay times of main luminescence transitions were measured at room temperature. A strong emission is reported at 1550 nm from the ( I 13 / 2 4 → I 15 / 2 4 ) transition, which intensity depends on the Er concentration.
