利用固相法制备蓝绿色荧光粉 Ca4Si2O7F2:Eu2+,并通过 XRD 和光致发光光谱对其性能进行表征.结果表明:Eu2+作为发光中心取代 Ca2+格位进入 Ca4Si2O7F2的晶格中,其最佳掺杂量为5%.激发光谱在360~440 nm 呈现出双峰宽带激发带,可与近紫外光 LED 芯片相匹配.在375 nm 和416 nm 激发下,样品呈现出峰值为506 nm 的不对称单一宽带发射.

Blue-green phosphors Ca4Si2O7F2:Eu2+ were prepared by solid phase method and characterized by XRD and photoluminescence spectrum. The results indicate that Eu2+ act as luminescence center into the crystal lattice of Ca4Si2O7F2. Its optimum doping concentrations is 5 %. Excitation spectrum is a broadband in the range of 360 nm to 440 nm, which matches with near ultraviolet LED ship. Under the excitation at 375 nm and 416 nm, only an asymmetric broadband at 506 nm is presented.
