以醋酸锌和尿素为主要原料,利用微乳-溶剂热法控制合成了棒状和球状ZnO微晶.用XRD、TEM、FTIR.和SAED等技术手段对两种形状的ZnO微晶进行了表征.结果表明:棒状ZnO微晶的平均尺寸为50nm×320nm,球状ZnO微晶的平均尺寸约为200nm.
ZnO microcrystals with rod-like and sphere-like morphologies were successfully synthesized by a emulsion-solvothermal method using Zn(CH3COO)2·2H2O and CO(NH2)2 as raw
materials and oleic acid and n-hexadecan as solution. The obtained ZnO microcrystals were characterized by XRD, TEM, FTIR and SAED. The rod-like ZnO microcrystals with an average size of 50nm×320nm
were prepared when the volume ratio of oleic acid and n-hexadecan was 1:6. The sphere-like ones with an average size of 200nm were obtained when the volume ratio of oleic acid and n-hexadecan
was 3:1. The method of this paper is simple, which may be a promising approach for the preparation of oxides with controlled morphologies.
