中文摘要：

通过对醋酸锌和三乙醇胺的水溶液微波辐照5min制得了半导体ZnO多孔纳米球。粉体用XRD、EDS、FESEM、TEM和HRTEM进行了表征。结果表明,ZnO多孔球为六方纤锌矿相结构,球直径在200～400nm之间,球表面富含有大量的孔隙。对比试验讨论了碱的浓度对晶体生长的影响,分析了可能的反应机理。室温下的PL光谱表明粉体在388nm处较强的激子发射和中心区在550nm处较宽的黄绿光发射。

英文摘要：

Semiconductor ZnO porous nanospheres have been successfully obtained through microwave irradiating the precursor aqueous solution of Zn（CH3COO）2·2H2O and triethanolamine（TEA,C6H15NO3）for 5min.The as-obtained powder was characterized by XRD,EDS,FESEM,TEM and HRTEM.The experimental results indicate that ZnO with hexagonal wurtzite structure are porous.The diameter of nanosphere is about 200-400nm, and there are abound of cavities on the surface of nanospheres.The possible formation mechanism associated with TEA concentrations and microwave reaction time is discussed.The room temperature PL spectrum showed a strong exciton emission with peak located at 388nm and a week broad yellow-green emission located at center of 550nm respectively.
