Preparation of Eu-doped LaPO4 films using successive-ionic-layer-adsorption-and-reaction

Abstract: Thin films of Eu-doped lanthanum orthophosphate (LaPO4) were fabricated on glass substrates using the successive-ionic-layer-adsorption-and-reaction method and subsequent hydrothermal and furnace annealing. A monoclinic structure was observed to be present in LaPO4:Eu films after hydrothermal annealing at 200°C. Scanning electron microscopy and transmission electron microscopy images of LaPO4:Eu films show the homogenously close-packed morphology of micro-sized nanofibers at around 10 to 20nm in diameter. The red emission activated at 254nm was obtained from LaPO4:Eu films. [Copyright &y& Elsevier]
