Development of Lateral Field Emission Type Light Emission Devices using Phosphor/ZnO Complex Nanorods Array

研究了基于场发射现象的新型发光器件的潜力。该器件采用在ZnO纳米棒上包覆荧光粉的复合纳米棒阵列。电场被横向地施加到阵列。阴极发射的电子在ZnO纳米棒阵列中运动时产生阴极发光。虽然获得发光所需的电压为几kV，但工作电流低于1mA。这种发光器件已经显示出低功耗前景。

The potential of a novel light emission device based on fieldemission phenomenon was studied. This device uses the array composed of the complexnanorods which prepared by coating phosphor on ZnO nanorods. An electric field islaterally applied to the array. The electrons emitted from a cathode electrode causedcathode luminescence while the electrons move through ZnO NRs array. Although theapplied voltage to obtain luminescence was several kV, operation current was below1mA. This light emission device have shown promise for low power consumption.
