| 摘 要： | 通过超声-微波辅助醇盐水解沉淀法合成了Yb:YAG与Nd:YAG纳米晶。研究了微波辐射功率、微波辐射时间及煅烧温度对产物的影响。采用X-射线粉末衍射(XRD)、扫描电子显微镜(SEM)、高分辨透射电子显微镜(HRTEM)及光致发光谱(PL)等对Yb:YAG与Nd:YAG纳米晶进行表征。结果表明，在微波辐射功率385 W、微波辐射时间30 min、煅烧温度1100 C条件下，可以获得纯相Yb:YAG与Nd:YAG纳米晶。当煅烧温度为1100 C时，Yb:YAG与Nd:YAG纳米晶的合作发光强度均达到最大值。

| Abstract: | Yb:YAG and Nd:YAG nanocrystals were synthesized by ultrasound-microwave-assisted alkoxide hydrolysis precipitation method. The effect of reaction parameters including the microwave radiation power, microwave radiation time and calcination temperature on the composition of the products was investigated. The Yb:YAG and Nd:YAG nanocrystals were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and photoluminescence (PL) spectrum. The results show that the pure phase Yb:YAG and Nd:YAG nanocrystals can be obtained at microwave radiation power of 385W, microwave radiation time of 30 min and calcination temperature of 1100 C. The cooperative luminescent intensities of the Yb:YAG and Nd:YAG nanocrystals reached the maximum at the calcination temperature of 1100 C. |
