Yttrium Oxide Luminescence Films Preparated by Electrodeposition- Sinter Method

Abstract:

Luminescence film material plays a very important role in display technology. In this paper, electrochemical deposition of luminescent Y₂O₃:Eu or Y₂O₃:Tb thin films on transparent conducting optically ITO glass substrates by cathodes reduction of yttrium nitric was investigated. Y(OH)₃ deposits were obtained using a conventional three electrode cell that potential of work electrode was –1.2v vs. Ag/AgCl electrode for 400 s in a 0.1mol/L Y(NO)₃ with 4%(mol/mol) Eu(NO)₃ at 65°C.Then this glass was sintered for 2h at 500°C.The luminescence spectrum of the film prepared by this method was tested. Its luminescent spectrum is the same as that of powder which prepared by solid method. Its XRD confirmed the formation of Y₂O₃ and SEM revealed uniformity of film.
