Zusammenfassung:3+233+65202+45.54+11172+65202+45.54+A phosphor blend for a compact fluorescent lamp is described wherein the phosphor blend comprises a green-emitting Tb phosphor, a YO:Eu phosphor, a SrBPO:Eu phosphor, a MgGeOF:Mn phosphor, and optionally a BaMgAlO:Eu phosphor, wherein the blend contains from 1% to 20% by weight of the SrBPO:Eu phosphor and from 5% to 30% by weight of the MgGeOF:Mn phosphor. A compact fluorescent lamp having a phosphor coating containing the phosphor blend produces a light that is perceived as more pleasing than the light produced by standard compact fluorescent lamps.
