摘要：

A high-luminance green-emitting electroluminescent (EL) device fabricated using a manganese-activated zinc gallate (ZnGa2O4:Mn) thin-film phosphor in conjunction with a thick barium titanate ceramic insulator has been demonstrated, The green emission was observed in EL devices fabricated using as-deposited ZnGa2O4:Mn thin films prepared by rf magnetron sputtering. A higher luminance was attained for EL devices fabricated using Zn Ga2O4:Mn thin films postannealed at 1020 degrees C in an argon atmosphere. A luminance of 710 cd/m(2) and a maximum luminous efficiency of 1 lml/W were obtained for a ZnGa2O4:Mn thin-film EL device driven by a sinusoidal voltage at 1 kHz. The device when driven at 60 Hz exhibited a luminance of 230 cd/m(2).
