Definitions

  • New Eu 3+ -doped uranyl compounds according to the invention are particularly suitable as radiation converters in blue light or UV light emitting semiconductor light sources and thus solve the object stated at the outset in an excellent manner.
  • the phosphors of the present invention surprisingly follow in sequence of an unexpectedly efficient energy transfer between the [UO2] 2+ cation and the Eu 3+, an emission with a red color point in the red.
  • the lumen is a photometrical photometric quantity which is familiar to the person skilled in the art and which measures the luminous flux of a light source which is a measure of the total visible radiation emitted by a radiation source Radiation is, describes. The larger the luminous flux, the brighter the light source appears to the observer.
  • a lighting unit in particular for the backlight of display devices, characterized in that it contains at least one light source according to the invention, and a display device, in particular liquid crystal display device (LC display), with a backlight, characterized in that it comprises at least one lighting unit according to the invention contains.
