Application of indium nanowires to donor–acceptor pair luminescence

A novel, self-supported nanostructured powder electroluminescence (EL) device, consisting of a dilute layer of conductive nanowires, which directly contacts a ZnS phosphor layer and functions as rear electrodes, is reported in this paper. Indium nanowires fabricated by using a porous alumina template and hydraulic pressure injection technique induce a localized field in the phosphor that is much higher than the average applied field and hence …
