    摘要： The present invention relates to Luminescent nanoparticles comprising

    (a) a core made from a luminescent metal salt selected from phosphates, sulfates or fluorides, being surrounded by
    (b) a shell made from a metal salt or oxide capable of preventing or reducing energy transfer from the core after its electronic excitation to the surface of the nanoparticle, e.g. a shell made from a non-luminescent metal salt or oxide,
       which are characterized by higher quantum yields and can be used in various fields including light generation and security marking.

    摘要： The invention relates to a printing method according to which, during the printing process, one or more narrow nozzles eject a printing liquid, and to a printing liquid suitable for such a method. The invention is particularly suitable for forgery-proof printing on papers or articles. According to the invention, the printing liquid contains nanoparticles that can be induced to fluoresce or phosphoresce. Said nanoparticles are small crystalline particles that can be induced to fluoresce or phosphoresce on their own or when mixed with dopants. Individual dots (10, 12) can be printed by means of a printing liquid that contains said nanoparticles. Due to their small size of from 1 to 1000 nanometers, preferably in the range of 300 nanometers or even much smaller depending on nozzle diameter, there is no risk of very narrow ink jet nozzles getting plugged. The induction and fluorescence emission frequency ranges are narrow-band so that for a security control of the print the respective wavelength-specific induction or detection is required, thereby increasing protection against forgery.

    摘要： The invention relates to a dental material, which contains surface-modified nanoparticles with an average particle size of less than 25 nm in the form of a filler, said nanoparticles being selected from the salts of barium, strontium, rare-earth metals, scandium or yttrium, or from wolframates. The surface of said nanoparticles is modified by an organic compound that bonds with the nanoparticles by means of a functional group containing N, P, S and/or O. Said dental material exhibits an excellent X-ray opacity, in addition to important processing characteristics such as transparency or dispersion stability.
