Abstract:
1. Method for dyeing a layer of a nanocrystalline material on a substrate using a liquid dye, comprising the successive steps of (i) providing said layer on a substrate; (ii) providing an apparatus for dyeing said layer, which apparatus comprises at least a supply container for the liquid dye, a closable substrate holder for a substrate provided with a layer of nanocrystalline material, the substrate holder being provided with at least one inlet and at least one outlet being connected via a circulation line to the supply container, which apparatus further comprises conduit and circulation means for causing the liquid dye to circulate through the supply container and the substrate holder and to flow against the layer of nanocrystalline material; (iii) placing the substrate with said layer in the substrate holder and closing the substrate holder, and providing a liquid dye in the supply container; and (iv) causing the liquid dye from the supply container to circulate for a determined time through the substrate holder and to flow against the layer of nanocrystalline material.
