Abstract

The invention provides a thin film comprising successive layers of aluminium oxide, aluminium oxynitride and aluminium nitride, which varies sinusoidally throughout the depth of the film. The film can be used to coat and protect tools with sharp working edges, to provide a stress free thermal protective coating for natural or man-made diamonds, as a light filter and/or as a pigment. It is made by sputtering aluminium using a suitable noble gas in a variable atmosphere of oxygen and nitrogen at room temperature. The film is transparent and has a refractive index which varies between 1.6 to 2.2, again sinusoidally with depth.
