| 摘 要： | 采用醇解法,在130℃的甲醇溶液中分别合成纯的和Al掺杂纳米氧化锌(ZnO)晶体.使用X射线衍射仪,透射电子显微镜,Fourier红外光谱和偏振稳态荧光光谱对其晶体结构和光学性能进行了表征.结果表明:在甲醇溶液中,在较低的温度(130℃)下,成功制备出纳米ZnO晶体.Fourier红外吸收光谱表明醇解法合成的ZnO纳米晶体含有较少的有机物杂质.荧光光谱结果可以看出,纯ZnO和Al掺杂的ZnO纳米晶体在可见光范围(400nm～700nm)内有一个高的蓝光发光带(峰位为440nm)和一个绿光发光带(纯的和Al掺杂的峰位分别为520nm和530nm).通过对比发现掺杂Al可以有效的改变ZnO纳米粉体的可见光发光特性.

| Abstract: | Undoped ZnO and Al doped ZnO nanocrystals were synthesized by the methanol alcoholysis method at 130℃.Structure,morphology and optical properties of ZnO nanocrystals were characterized using X-ray diffraction,transmission electron microscopy(TEM),Fourier transform infrared(FTIR) and photoluminescence(PL) spectra.The results show that ZnO nanocrystals can be obtained in methanol solution at low temperature(130℃).FTIR spectra show that ZnO nanocrystals synthesized by the methanol alcoholysis include a little organic impurity.PL spectra reveal that pure ZnO and Al doped ZnO nanocrystals have a blue band emission at 440 nm and a green band emission at 520 nm and 530 nm,respectively.Compared with the pure ZnO nanocrystals,the Al doping improves the luminescent properties. |
