    • 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.
    • 本发明涉及一种基于Xe或Xe / Ne准分子放电的发光器件,例如, 全彩显示屏或氙准分子灯,其包括发射Eu(III)活化荧光体和UV光发射荧光体的荧光体共混物。 根据本发明的全色等离子体显示面板(PDP)包括红色发射的Eu(III)激活的荧光体和用于红色像素的UV发光荧光体的荧光体混合物,其显示出改善的色点和较短的衰减时间 与使用各自的单个红色发射Eu(III)活化荧光体相比。 包含再发射Eu(III)激活荧光体和UV发光荧光体的荧光体共混物的用于照明目的(例如用于LCD背光或X射线图像照明)的氙准分子灯显示出改进的显色性。 本发明还涉及发射Eu(III)激活的荧光体和UV发光荧光体的荧光体共混物。
