摘要：

Multicomponent oxide phosphors such as Mn-activated CaO-Ga2O3 are demonstrated to be very promising as the thin-film emitting layer for thin-film electroluminescent (TFEL) devices. The EL emission color from CaO-Ga2O3:Mn TFEL devices changed from green to orange as the CaO content was increased from 0 to 100 mol%. A Ga2O3:Mn TFEL device driven at 1 kHz produced a green emission with a luminance of 232 cd/m(2). A yellow emission with a luminance of 1725 and 261 cd/m(2) was obtained in a TFEL device using a CaGa2O4:Mn thin film prepared with a CaO content of 50 mol%, when driven at 1 kHz and 60 Hz, respectively.
