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.
