BaClF:Eu^(2+)的微波辐射合成

Microwave Irradiation Synthesis of the BaClF:Eu 2+ Phosphor

报道了用微波辐射法合成了ＢａＣｌＦ：Ｅｕ２＋荧光体，Ｘ－射线粉末衍射测定其相结构为四方晶系，晶胞参数为ａ＝０．４３８９３ｎｍ，ｃ＝０．７２２３ｎｍ，测定了最大激发峰和最大发射峰；在２５４ｎｍ光激发下，测定了色坐标。

The BaClF:Eu 2+ phosphor had been synthesized by the microwave irradiation method. The X ray powder diffraction data showed that its structure belonged to tetragonal system whose lattice parameters were a=0.43893nm and c=0.7223nm. The maximum excitation spectrum and the maximum emission spectrum had been measured. Under 254nm exitation, the chromatic coordinates of the phosphor were measured.
