Abstract
Thin films of Eu-doped lanthanum orthophosphate (LaPO 4) 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 LaPO 4:Eu films after hydrothermal annealing at 200 °C. Scanning electron microscopy and transmission electron microscopy images of LaPO 4:Eu films show the homogenously close-packed morphology of micro-sized nanofibers at around 10 to 20 nm in diameter. The red emission activated at 254 nm was obtained from LaPO 4:Eu films.
