| 摘 要： | 通过溶胶-凝胶（Sol-Gel）法制备了碱土金属多铝酸盐荧光粉Ba0.5MgyAl12-xMnxO19，其中0.1≤x≤0.8, 0.3≤y≤1.0。利用差热分析和XRD等实验技术，研究了荧光粉的形成过程及合成条件。确定最佳烧结温度为1250℃，灼烧时间为3.5～5h。通过分光光度计测定了其发光性能，发光体的最大发射峰波长位于676nm。通过透射电镜可知，发光体的粒径在20～60nm之间，属纳米级发光材料。

| Abstract: | Ba0.5MgyAl12-xMnxO19 was synthesized by Sol-Gel method and the phase of the synthesized material was analyzed by using x-ray diffraction. The reaction process was characterized by TG-DTA at different temperatures ranging from the room temperature to 1200℃. The optimal calcinated temperature and time are 1250℃ and 3.5～5h, respectively. The luminescence was detected by a phosphor luminometer (PL). The maximum emission peak is at 676nm when fired at 1250℃, corresponding to the red light. Ba0.5MgyAl12-xMnxO19 powder is a nano crystal with diameter ranging from 20 to 60nm testified by using TEM. |
