摘要
CeMgAl11O19 phosphor was prepared by combination of the chemical precipitation and high temperature ball milling method. The sintered temperatures of these two methods were compared. Meanwhile, the particle distribution and X-ray diffraction (XRD) analysis was carried out and the optimally prepared process was found. Experimental results showed that the orbed CeMgAl11O19 phosphor with average size of about 40 nm and homogeneously distributed was achieved by the process which involved preparing precursor with chemical precipitation method, drying the precursor and ball milling at 900°C. Compared with chemical precipitation or high temperature ball milling method, the sintering temperature was decreased effectively with this process.
