Abstract: 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.

Abstract: The invention relates to UV emitting nanoparticles for radiation therapy purposes. If the nanoparticles are brought indirectly or directly to the diseased tissue, excitation with high energy radiation leads to VUV or UV-C emission. This UV radiation is absorbed by the surrounding organic matrix, resulting in decomposition of the material. The nanoparticles can also be modified by attaching antibodies to the particles by chemical linking or coating. Preferably these antibodies bind specifically to the cell membrane of cancer cells leading to a localised destruction of diseased tissue with a high efficacy and a lower level of destruction of surrounding healthy tissue. Endoscopic detection of the UV emission can be used as a medical imaging technique to locate and study diseased tissue.
