Widely adjustable optical functional layer e.g. as UV protection for plastic films glass textiles food - Effective UV-A protection from 320-470n


By means of a novel method it was possible to create by making full use of the Bowing effect against prevalent views a ternary compound whose absorption edge can be freely adjusted over a wide range and which features a sharp absorption edge (e.g. ZnOxS(1-x) with c. 320 470 nm 26-38eV UV-B range). To do so the novel method uses production methods which have already been established (thin layer deposition) particularly advantageous sputter and chemical deposition techniques.


Very "widely adjustable" range of the absorption edge very "sharp" absorption edge. Relatively non-expensive production due to the utilization of established methods
