A SUBSTRATE COATED WITH AMORPHOUS HYDROGENATED CARBON
摘要
<p>The invention relates to a substrate being at least partially coated with a coating comprising at least a first layer and a second layer. The first layer and the second layer comprise amorphous hydrogenated carbon. The first layer has a first Eo4 optical band gap and the second layer has a second Eo4 optical band gap. The said second Eo4 optical band gap is smaller than said first Eo4 optical band gap. The invention further relates to a method to deposit such a coating on a substrate.</p>
