Owing to the specific properties such as high mobility, ballistic carrier transport and light emission, carbon nano-particles (CNPs) have been employed in nanotechnology applications. In the presented work, the CNPs are synthesized by using the pulsed arc discharge method between two copper electrodes. The rectifying behaviour of produced CNPs is explored by assuming an Ohmic contact between the CNPs and the electrodes. The synthesized sample is characterized by electrical investigation and modelling. The current–voltage (I–V) relationship is investigated and bright visible light emission from the produced CNPs was measured. The electroluminescence (EL) intensity was explored by changing the distance between two electrodes. An incremental behaviour on EL by a resistance gradient and distance reduction is identified.
