The present invention relates to a composite luminophore comprising an inorganic matrix and an organic fluorescent dye, wherein the inorganic matrix is formed from an inorganic compound, and wherein the organic fluorescent dye has one or more functional groups by means of which the fluorescent dye is incorporated into the inorganic matrix, or is bound chemically thereto. The present invention further relates to a process for preparing such a composite luminophore and to the use thereof.

A method for manufacturing a photo-responsive device having a photo-sensitive layer is proposed. The method comprises the following steps: a) providing a clean substrate inside an evacuated evaporation chamber; b) evaporating lead oxide (PbO) from a first crucible to form a seeding layer on the surface of the substrate; c) affecting upon the seeding layer such that only tetragonal lead oxide forms the seeding layer and/or such that the initially grown orthorhombic lead oxide forming the seeding layer is transformed into tetragonal lead oxide; and d) continuing to evaporate lead oxide until the final thickness of the photo-sensitive layer has been deposited onto the substrate. As a result the method yields a photo-responsive device comprising a photo-sensitive layer of lead oxide, which entirely consists of tetragonal lead oxide.

Lead oxide based photosensitive device and its manufacturing method

A method for the production of Mg(OH)nanoparticles, by means of polyol-mediated synthesis, from an Mg precursor as well as a base. The particles produced with this method have a diameter between 10 nm to 300 nm, have a mono-disperse particle distribution, and are present in non-agglomerated form. They can be converted to MgO particles by means of calcination.
