Delayed luminescence from ZnO ceramics upon microwave-induced plasma emission Original Research Article

A delayed luminescence from the ZnO ceramics upon microwave-induced plasma emission was observed and its hybridized excitation mechanism was investigated. A phenomenological model of the luminescence is proposed to explain the occurrence of the hybrid excitation process and confirmed that the hybridization is by the photon of luminescence through atomic plasma emission and by the microwave depending on its power. This finding provides a distinctive methodology for studying the physics of the interaction between microwave and matter.
