RARE EARTH ELEMENTS DOPING ON YTTRIUM OXIDE LUMINESCENT THIN FILM CONTAINING CONDUCTIVE OXIDES AND PREPARATION METHODS THEREOF

摘要

A rare earth elements doping on yttrium oxide luminescent thin film containing conductive oxides and preparation methods thereof are provided. The said luminescent thin film is consisted of Y₂O₃:Re, Zn_1-xAl_xO, wherein 0x≦0.05, Re═Eu or Th. The said methods include the following steps: step 1, preparing colloid of Y and Eu or colloid of Y and Tb; step 2, preparing colloid of Zn_1-xAl_xO; step 3, mixing the colloid in step 1 and the colloid in step 2 to form complex colloid; step 4, coating the complex colloid in step 3 to form the luminescent thin film. The said luminescent thin film increases the conductivity and luminescent property of yttrium oxide luminescent thin film in the art.
