| Abstract: | SrGa2S4: Ce blue TFEL device with a novel structure was prepared by electron beam evaporation. The dielectric constant of insulator layer in this structure is far less than that in the conventional structure, so the hot-electrons can be accelerated in SiO2 layers. The stable TFEL with good chromaticity was achieved and the basic characteristics were investigated. |
