The invention concerns a transparent substrate whereof part at least of the outer surface has the form of a web comprising protuberances, 80% of them at least, having heights ranging between 40 and 250 nm, mean diameters between 1 and 500 nm, 80% at least of the distances between two neighboring protuberances ranging between 1 and 500 nm. The invention further provides two methods for making said substrates and its use in a transport vehicle glazing, for a building, or for an indoor or outdoor decorative element, for urban environment or for household appliance, in a lenticular screen or microprism substrate, in an engraved glass substrate for lamp or display, and in a chemical or biochemical microreactor.
