    • The invention relates to a gas discharge lamp for dielectrically impeded discharges, which gas discharge lamp is provided with a discharge vessel filled with a gas filling, which discharge vessel comprises at least a wall of a dielectric material and at least a wall having a surface which is at least partly transparent to visible radiation and coated with a phosphor layer, which phosphor layer comprises a phosphor having a host lattice, Eu2+ as the activator and a doping D selected from the group formed by Ce3+, Pr3+ and Tb3+, and provided with an electrode structure for a dielectrically impeded discharge and means for igniting and maintaining the discharge. The invention also relates to a phosphor comprising a host lattice, Eu2+ as the activator and a doping D selected from the group formed by Ce3+, Pr3+ and Tb3+.
    • 本发明涉及一种用于介电阻塞放电的气体放电灯,该气体放电灯设置有填充有气体填充物的放电容器,该放电容器至少包括介电材料的壁和至少一个具有表面的壁 对可见辐射至少部分透明并涂覆有磷光体层,该荧光体层包含具有主体晶格Eu 2+作为活化剂的磷光体和选自Ce 3+形成的基团的掺杂D, Pr <3+>和Tb <3+>,并具有用于介电阻碍放电的电极结构和用于点燃和保持放电的装置。 本发明还涉及包含主晶格Eu 2+作为活化剂的磷光体和选自Ce 3+,Pr 3+和Tb 3+的基团的掺杂D。
