Abstract

Abstract: The flat panel display is the development direction of display technology.Filming luminescence material possess important position in display technology.In this paper,electrochemical deposition of red luminescent Y₂O₃:Eu thin films on transparent conducting optically(ITO) glass substrates by cathodic reduction of yttrium nitric has been investigated.Y(OH)₃ deposits were obtained using a conventional three electrode cell that potential of work electrode was -1.2 V vs.Ag/AgCl electrode for 400 s in a 0.1 mol/L Y(NO)₃,with 4%(mol/mol) Eu(NO)₃,temperature 65 ℃.Then the glass coated Y(OH)₃ containing Eu sintered for 2 h at 500 ℃.The luminescence spectrum of film preparated by this method was similar compared with that of the powder preparated by solid methed.XRD confirms the formation of Y₂O₃ and SEM reveal uniformity of film.

Key words: electrodeposition-sinter method, film, Y₂O₃:Eu, luminescence
