METHOD FOR FORMING A DECORATIVE COATING ON A GEMSTONE, A DECORATIVE COATING ON A GEMSTONE, AND USES OF THE SAME |
摘要 |
<p>A decorative coating and a method for forming a decorative coating on a gemstone to change the natural visual appearance of the gemstone. The decorative coating comprises an optically absorbing film. Depositing the absorbing film on the substrate comprises the alternating steps of introducing a first precursor to the reaction space such that at least a portion of the first precursor gets adsorbed onto the surface of the substrate, and subsequently purging the reaction space, and introducing a second precursor to the reaction space such that at least a portion of the second precursor reacts with the portion of the first precursor adsorbed onto the surface of the substrate to form a conformal absorbing film on the substrate comprising the gemstone, and subsequently purging the reaction space. The material of the absorbing film is selected from the group of oxides, carbides, noble metals or a mixture thereof.</p> |
