系统分析了水热温度、保温时间对锗酸锶纳米线形成的影响。扫描电子显微镜和X-射线衍射分析结果表明水热温度和保温时间对锗酸锶纳米线的形成与生长起到了重要作用。随着水热温度的增加,锗酸锶棒状结构的长度不断增加,由无定形结构转变为了斜方SrGeO3晶相。随着保温时间的增加,锗酸锶纳米线的长度由10微米增加至了数十微米。通过晶体核化与生长机制可以解释锗酸锶纳米线的形成。
The influence of hydrothermal temperature and holding time on the formation of strontium germanate nanowires was systematically analyzed. Scanning electron microscopy and X-ray diffraction analysis showed that hydrothermal temperature and holding time played an important role in the formation and growth of strontium germitate nanowires. With the increase of hydrothermal temperature, the length of strontium germanate stroma increases from amorphous to orthorhombic SrGeO3. With the increase of holding time, the length of strontium germanate nanowires increased from 10 μm to several tens of micrometers. The formation of strontium germitate nanowires can be explained by the mechanism of nucleation and growth of crystals.
