摘　　要：以牛血清白蛋白(BSA)这种可溶性生物大分子蛋白为模板,在室温下成功制备了多孔蜂巢状碱式碳酸锌薄膜。经过低温退火后得到了具有良好电子迁移率的高比表面积多孔ZnO薄膜。经SEM、TEM、XRD、光致发光光谱和紫外-可见吸收光谱等测量手段,分别对碱式碳酸锌薄膜及其退火后的ZnO薄膜进行表面形貌、结晶性能以及光致发光特性分析。通过对无蛋白质薄膜诱导所得的样品进行比较,判断BSA分子与Zn^(2+)离子之间的络合作用是碱式碳酸锌多孔薄膜合成的首要因素。实验表明该方法制备的ZnO薄膜样品具有高比表面积和在近紫外范围的宽带发光特性。Honeycomb-like films of basic zinc carbonate were successfully prepared on FTO(SnO_(2):F)conductive glass using bovine serum albumin(BSA)as a template at room temperature.After low-temperature annealing,a high-specific-surface-area porous ZnO film with excellent electron mobility was obtained.The surface morphology,crystallization performance,and photoluminescence characteristics of basic zinc carbonate thin films and annealed ZnO thin film were analyzed by scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray diffraction(XRD),photoluminescence spectroscopy(PL)and UV-Visible spectroscopy(UV-vis).By comparing with those samples prepared without any protein,it was determined that the complexation between BSA molecules and Zn^(2+)ions was the primary factor in the synthesis of porous films of basic zinc carbonate.The experimental results showed that the ZnO thin film samples prepared with this method had high specific surface area and broadband luminescence characteristics in the near ultraviolet range.
