铟掺杂氧化锌基纳米材料的合成与表征

The Synthesis and Characterization of Indium-doped ZnO-based Nanomaterials

以微波诱导燃烧法合成了铟掺杂氧化锌纳米材料。考察掺杂量对产物性能的影响;采用XRD,SEM,PL等测试手段对产物进行了表征,结果表明:367nm处的氧化锌的紫外峰外发射峰是由峰位的蓝移造成的,且由于氧空位形成的浅施主能级朝着价带的跃迁引起了450nm、470nm、490nm处蓝光发射峰。铟掺杂量为40%时得到的氧化锌纳米材料呈花瓣状、结晶度高、分布均匀、荧光性能最优。

The Indium-doped Zn O-based nanomaterial is synthesized through microwave-induced combustion. In order to investigate the effect of the amount of Indium doped to the material on the properties of synthesized sampler,testing methods of XRD,SEM and PL are used to characterize the properties of the sample respectively. The results indicate that the UV emission peak in 367 nm is due to the Zn O UV emission peak occurring blue shift,and it is likely that blue light emission peaks in 450 nm,470nm,and490 nm are inspired by shallow benefactor level formed oxygen vacancies jumping to valence band. When the amount of Indium doped reaches 40%,Zn O-based nanomaterial looks like petals with high crystallinity,uniform distribution and fluorescence properties of the optimal.
