摘要

The green emission intensity of ZnGa2O4:Ge4+, Li+, Mn2+ excited by the vacuum ultraviolet line of 147 nm reaches 70% of commercial green Zn2SiO4:Mn2+. The vacuum ultraviolet excitation spectra consist of four peaks. In a plasma display test bed filled with Ar and Ne plasma discharged by a radio-frequency generator of 13.6 MHz, ZnGa2O4:Ge4+, Li+, Mn2+ and commercial Zn2SiO4:Mn2+ phosphor screens show a linear increase in luminance with increasing self bias voltages. Increasing gas pressures cause the luminance to increase. Also, on increasing the self bias voltages and the gas pressures, the current densities of ZnGa2O4:Ge4+, Li+, Mn2+ phosphor screens are increased; this is the same behavior as that of the commercial phosphor.
