    Abstract: Disclosed are compositions and methods for producing carbon-based films, for example, ultra smooth diamond nanostructured diamond films. Generally, the disclosed compositions can comprise a noble gas component, hydrogen, a carbon precursor, and nitrogen. Generally, the disclosed methods can comprise the steps of providing a mixture comprising a noble gas, hydrogen, a carbon precursor, and nitrogen, establishing a plasma comprising the mixture; and depositing carbon-containing species from the plasma onto the surface, thereby producing a film on the surface. Generally, the disclosed films exhibit superior average gain size, RMS surface roughness, hardness, relative diamond crystallinity, and surface adhesion.
