    Abstract

    Luminescent properties and co-dopant effects of manganese-activated MgGa2O4 phosphor were investigated under VUV excitation. MgGa2O4:Mn exhibited an intense green emission with the spectrum centered at 503 nm and the sensitizer Eu and Ce improved the radiant efficiency and decay time characteristics. In addition, the excitation efficiency strongly depends on the bonding energy and degree of inversion of host materials. In case of optimum compositions, manganese-activated MgGa 2O4 phosphor could be one of the potential green-emitting PDP phosphors.
