| 摘 要： | 前躯体ZnS在超声辅助60℃的低温条件下,采用醋酸锌为锌源、硫代乙酰胺为硫源来制备,然后采用在空气中热处理前躯体ZnS的方法制备了直径约为20~40 nm的ZnO纳米颗粒。所得产物分别采用红外光谱(FTIR)、热重-差热分析(TGA-DTA)、X射线衍射(XRD)、场发射扫描电镜(FE-SEM)、透射电镜(TEM)、电子能谱(EDS)和荧光光谱(PL)进行表征。实验结果表明,所得产物ZnO为六方纤锌矿结构,且结晶性很好,并且随着超声时间的延长其粒径有所降低。室温PL光谱表明,样品在400~550 nm内有3个较强的荧光发射峰。 |

| Abstract: | ZnO nanoparticles with an average size of about 20～40 nm were synthesized by thermal treatment of ZnS nanoparticles under atmospherical condition.The ZnS nanoparticles had been synthesized at a low temperature of 60 ℃ by using zinc acetate as a zinc source and TAA as a sulfur source with the aid of ultrasonic.The as-prepared products were respectively characterized by means of Fourier transformed infrared spectra(FTIR),Thermal gravimetric analysis and differential thermal analysis(TGA-DTA),X-ray diffraction study(XRD),Field-emission scanning electron microscopy(FE-SEM),Transmission electron microscopy(TEM),EDS and Photoluminescence(PL) spectra.The results reveal that the ZnO nanoparticles are of hexagonal wurtzite structure,of high crystallinity and the size of the ZnO nanoparticles decreases with the increment of the ultrasonic time.The room temperature PL spectra reveals three strong emissions with peaks located within the range of 400～550 nm. |
