Abstract
Disclosed is a method for the production of diamond films, which comprises introducing a diamond-forming gas into a reaction chamber in which a substrate is located, activating the gas in the reaction chamber and depositing diamond on the substrate by decomposition of the gas, wherein the diamond-forming gas is a gas or gas mixture containing hydrogen, oxygen and carbon atoms at an atomic ratio satisfying requirements represented by the following formulae: EQU 2.gtoreq.C/H.gtoreq.0.0005, and EQU 4.gtoreq.O/C.gtoreq.0.0005.
