采用传统的高温固相反应法制备了一系列Eu2+掺杂的Sr6BP5O20荧光粉。研究了它们在紫外光和低压电子束激发下的光致发光。可以观察到最大波长约为480 nm的青色发射带。色品坐标分析表明，与三基色荧光粉相比，该荧光粉能明显扩大色域。结果表明，Sr6BP5O20：Eu2+有可能成为场发射显示器（FED）的潜在候选材料。
A series of Eu2+doped Sr6BP5O20phosphors were prepared by a traditional high temperature solid state reaction method. Their photoluminescence under ultraviolet (UV) light and low-voltage electron beam excitation were investigated. Cyan emission band with a maximum wavelength at about 480 nm can be observed. The chromaticity coordinates reveal the phosphor can evidently enlarge the gamut compared with tricolor phosphors. The results show that Sr6BP5O20:Eu2+may be a potential candidate for field emission displays (FEDs).
