中文摘要：

通过高温固相反应在空气中制备了一系列Eu^2＋掺杂的BaMgSiO4∶Eu^2＋发光材料,研究了其发光性能及M2CO3（M=Li、Na、K）助溶剂对其性能的影响。利用X射线粉末衍射（XRD）、荧光光谱（PL）和扫描电镜（SEM）对合成的样品进行表征。研究表明,Eu^2＋进入Ba（1）和Ba（2）位置有利于Eu^2＋在空气中稳定存在。M2CO3（M=Li、Na、K）助溶剂促进Eu3＋离子在空气中还原成Eu^2＋离子,提高了BaMgSiO4∶Eu^2＋的发光强度。当Na2CO3用量为6%时,BaMg-SiO4∶Eu^2＋的发光强度达到还原气氛中制备的91%。

英文摘要：

A serials of Eu^2＋ -doped BaMgSiO4：Eu^2＋ phosphors were prepared in air by high temperature solidstate reaction.The effects of alkali carbonate on the PL properties of BaMgSiO4：Eu^2＋ prepared in air were investigated by X-ray diffraction（XRD）,photoluminescence（PL）and scanning electron microscope（SEM）.The results showed that Eu^2＋ ions located in Ba（1）and Ba（2）could be in favor of stable existence in air.The PL intensity of BaMgSiO4：Eu^2＋ prepared in air was increased by adding M2CO3（M=Li,Na,K）flux,and the PL intensity of BaMgSiO4：Eu^2＋ phosphors containing 6% Na2CO3 prepared in air was the 91% of that prepared in reducing atmosphere.
