Abstract

The photoluminescent (PL) and electroluminescent (EL) characteristics from Y_2O_3:Mn thin films prepared by sol-gel process, PLD or r.f. magnetron sputtering were found to be strongly dependent on the deposition method as well as the preparation conditions of the thin films. The difference of luminescent characteristics were mainly attributed to the crystal structure of the resulting Y_2O_3:Mn thin films. When the crystal structure of Y_2O_3:Mn thin films was monoclinic, both the PL and EL emissions were observed. But the PL and EL emissions was not observed in Y_2O_3:Mn thin films of which the crystal structure was cubic. High-luminance PL and EL emissions were realized by controlling the crystal structure of the Y_2O_3:Mn thin film.
