摘要
为了寻求廉价荧光粉,采用燃烧法于850℃合成了自激发蓝绿色荧光粉X_3(VO_4)_2(X=Sr,Ba),研究了燃烧温度对荧光粉发光强度的影响,并用XRD、TEM和荧光/磷光分光光度计对该荧光粉的物相、形貌及发光性能进行了表征和研究.结果表明:在340 nm激发下可得到一个400～600 nm宽发射峰.
The phosphors, X3（VO4）2（X=Sr, Ba） have been successfully synthesized by combustion method at 850 C for the first time. The influence of combustion temperature on fluorescence intensity of phosphors have been studied. The samples were characterized by X-ray powder diffractometer （XRD）, transmission electron microscopy （TEM） and luminescence spectrometer （LS）. The results showed that under the excitation of 340 nm, the phosphor exhibits broad band emission ranging from 400 to 600 nm.
