摘　　要：使用Zn（CH3COO）2·2H2O和PVA水溶液混合的办法在Si衬底上生长了微孔结构的ZnO薄膜。样品的晶体结构、形貌及光致发光性使用XRD、SEM及PL谱进行表征。结果表明所制备的ZnO为六方纤锌矿型晶体结构，微孔的孔壁是由纳米颗粒聚集而成，颗粒尺寸大约为20nm,关于这种结构的形成，我们推测PVA在微孔结构的形成过程中起到了模板作用。Microporous structure ZnO thin films were synthesized on Si substrate via blending Zn（CH3COO）2.2H2O and PVA aqueous solution. Crystal structure, morphology and photoluminescence property were characterized by XRD, SEM and PL spectra. XRD indicates that as-synthesized sample is wurtzite structure. It＇s observed that the walls of porous structure were assembled by ZnO nanoparticles. The particle size is about 20nm. We guess PVA plays an important part in the formation of the structure, serving as the soft template.
