    • Disclosed is a fluorescent composition for a low-pressure discharge lamp having great light efficiency and a high color temperature. Said fluorescent composition contains fluorescent materials emitting in the red wavelength range from the group comprising europium-doped yttrium oxide and cerium-doped and manganese-doped gadolinium zinc magnesium pentaborate, fluorescent materials emitting in the green wavelength range from the group comprising cerium-doped and terbium-doped lanthanum phosphate and/or terbium-doped cerium magnesium aluminate and/or terbium-doped cerium magnesium pentaborate, as well as an optional fluorescent material of the type europium-doped barium magnesium aluminate, which emits in the blue wavelength range. The invention is characterized in that the fluorescent composition additionally contains at least one fluorescent material emitting in the blue or blue-green wavelength range from the group comprising manganese- doped and europium-doped manganese strontium barium magnesium aluminate or europium-doped and manganese-doped barium magnesium aluminate, europium-doped strontium aluminate, europium-doped strontium barium calcium chloroapatite, and europium-doped strontium borophosphate.
    • 公开了一种具有高光效和高色温的低压放电灯的荧光组合物。 所述荧光组合物含有从包含铕掺杂氧化钇和铈掺杂的锰掺杂的钆锌镁镁硼酸盐的组的红色波长范围内发射的荧光材料,从包含铈掺杂和 铽掺杂磷酸镧和/或铽掺杂的铈铝酸镁和/或铽掺杂的五硼酸铈镁,以及在蓝色波长范围内发射的铕掺杂的铝酸镁铝酸盐的任选的荧光材料。 本发明的特征在于,荧光组合物另外含有至少一种发射在蓝色或蓝绿色波长范围内的荧光材料,该荧光材料包括锰掺杂和铕掺杂的锰酸锶钡铝酸镁或掺杂铕的锰掺杂 铝酸钡铝,铕掺杂的锶铝酸盐,铕掺杂锶钡钙氯磷灰石和铕掺杂的硼酸锶。
