Ordered growth of ZnO nanorods for fabrication of a hybrid plasma display panel

Abstract

Ordered growth of a ZnO nanorod array on a pre-patterned ZnO seed layer was successfully obtained. This patterned array of ZnO nanorods was introduced to the front panel of a plasma display panel ( PDP), forming a hybrid PDP. The discharge voltages of a hybrid panel versus a conventional one were measured, showing significantly lower firing and sustaining discharge voltages. The reduction of discharge voltage was attributed to an enhanced effective secondary electron emission yield (gamma(eff)) by the presence of ZnO nanorods. The gamma(eff) of a hybrid panel was found to be higher due to the field-assisted electron emission under a PDP electrical field. The luminance and luminance efficiency of a hybrid PDP were also characterized and compared with those of a conventional panel.
