Fabrication of transparent and flexible carbon-doped ZnO field emission display on plastic substrate

Transparent and flexible carbon doped ZnO (C: ZnO) field emission device was successfully fabricated on an arylite substrate. Excellent adhesion of deposited C : ZnO on the flexible substrate was achieved with low sputtering power and Ar flow rate. In the fabricated device, nanostructured C : ZnO and as-deposited thin films were used as field emitter and phosphor screen, respectively. The C : ZnO thin film showed a transparency of about 80% at 550 nm wavelength and average sheet resistance of 1.96 k Omega/square The C: ZnO phosphor screen emitted red light during the field emission measurement, correlating the dominant cathodoluminescence peak at 646 nm. Thus, a promising transparent and flexible field emission display can be realized with C: ZnO based material. (C) 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
