Abstract:
This invention relates to a dielectric barrier Xe discharge lamp comprising an UV-B phosphor. The lamp consists of a gas-tight, discharge vessel with a gas filling containing Xe or a Xe/Ne mixture and is provided with a luminescent layer, which comprises at least one luminescent material emitting in the UV-B range (280 to 320 nm). The luminescent layer comprises a Gd activated phosphor according to the formulas McPO4:Gd, Lal1_XA13(BO3)4:GdX, and La1_xB3O6:Gdx which is eventually sensitised by Bi , Pr or Nd The advantages of such an UV-B emitting discharge lamp over fluorescent lamps based on a Hg low-pressure discharge are a high power density, 10 instant light, long lifetime, a spectral power distribution which is only determined by the phosphor blend, and an arbitrary burner design.
Abstract:
This invention concerns the application of inorganic luminescent nanoscale particles, which exhibit optical transitions in the visible spectral range, which can be exploited for excitation purposes and which show an emission band or lines in the NIR range, preferably between 650 and 1100 nm. These nanoscale particles are eventually coated by SiO 2 or other inert oxides, e.g. Al2O3, in order to decrease toxicity and to enhance particle lifetime in living systems.
