本文介绍了在较低温度下制备具有合成能力的前驱体粉末的方法。对初始粉末混合物进行机械力化学处理，作为后续高温处理前驱体的初步步骤。用X射线衍射仪、扫描电子显微镜和光致发光光谱对fic的比表面积、物相组成和发光性能进行了研究。结果表明，与基准样品相比，样品的发光温度降低了300◦C，但发光强度与合成温度有关。在1650◦C合成的粉末具有最高的发光强度。
The paper presents the method of preparation YAG:Ce precursor powder with ability for synthesis at lower temperature. Mechanochemical processing of an initial powder mixture was used as a preliminary step for subsequent high-temperature treatment of the precursor. The specific surface area, phase composition and luminescence properties were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy. It has been shown that YAG structure formed at lower temperature by 300 ◦ C in comparison to the reference specimen but luminescence intesity was dependant on temperature of powder synthesis. The highest luminescence intensity was observed for powders synthesised at 1650 ◦ C.
