Abstract
Copper phthalocyanine (CuPc) nanowires were prepared through simple chemical route at room temperature. As-synthesized samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscope. The self-assembly mechanism regarding the formation of copper phthalocyanine nanowires has also been presented here. Field emission of as prepared nanowires has been studied for a particular anode-sample spacing of 220 μm. The chemically synthesized CuPc nanowires portray a good field emission property with turn-on field of 7.6 V/μm and field enhancement factor (β) of 1512, which might have promising application as a competitive cold cathode material in field emitting microelectronic devices.
