摘要：
A phosphor blend for a compact fluorescent lamp is described wherein the phosphor blend comprises a green-emitting Tb3+ phosphor, a Y2O3:Eu3+ phosphor, a Sr6BP5O20:Eu2+ phosphor, a Mg4GeO5.5F:Mn4+ phosphor, and optionally a BaMgAl11O17:Eu2+ phosphor, wherein the blend contains from 1% to 20% by weight of the Sr6BP5O20:Eu2+ phosphor and from 5% to 30% by weight of the Mg4GeO5.5F:Mn4+ 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.
