Emission Spectroscopy of Carbon Laser Ablation in Methane Atmosphere

Abstract

Understanding plasma chemistry in methane by measuring kinetic and thermodynamic features of the ionic, atomic, and molecular emission in laser ablation plume is crucial especially for thin film synthesis of hydrogenated carbon. We report the emission spectroscopy of carbon plasma produced by ultraviolet nanosecond laser in a methane atmosphere. Atomic and molecular emitting species including C
