| 20090200915 | METHOD LIGHT EMITTING DEVICE WITH A EU(III)-ACTIVATED PHOSPHOR AND SECOND PHOSPHOR - This invention relates to a light emitting device based on a Xe or Xe/Ne excimer discharge, e.g. a full colour display screen or a xenon excimer lamp, comprising a phosphor blend of a red-emitting Eu(III)-activated phosphor and an UVlight emitting phosphor. Full colour plasma display panels (PDPs) according to the present invention comprising a phosphor blend of a red-emitting Eu(III)-activated phosphor and an UV-light emitting phosphor for the red pixels show an improved colour point and a shorter decay time compared to the use of the respective single red emitting Eu(III) activated phosphor. Xenon excimer lamps for illumination purposes (e.g. for LCD backlighting or X-Ray image illumination) comprising a phosphor blend of a redemitting Eu(III) activated phosphor and an UV-light emitting phosphor show an improved colour rendering. The invention is also related to a phosphor blend of a red-emitting Eu(III)-activated phosphor and an UV-light emitting phosphor. | 08-13-2009 |
