采用简便的旋涂过程和一步水热法在压电基片上制备了Ga掺杂的ZnO纳米薄膜(GZO).在水热处理过程中,通过添加不同的聚合物可形成纳米盘和纳米花状形貌的薄膜.采用场发射扫描电镜(Fe-SEM)、X射线衍射(XRD)和Raman光谱表征了样品的形貌、微结构和组成.XRD和FE-SEM结果证明,在AlN/Si压电基片上形成的纳米盘、纳米棒和纳米花状GZO均为纤维锌矿相.采用浸渍法进一步在所制GZO样品上固定了绿色的荧光蛋白质(GFP).运用原子力显微镜和荧光光谱分析了GFP与GZO表面结合的性质,考察了其用于传感器和生物成像技术的可行性.痕量GFP的固定使该材料产生荧光响应,表明其用于紫外光传感器时具有较好活性.
Ga-doped ZnO nanostructured thin films (GZO) were prepared on the piezoelectric substrate by a simple spin-coating process and one-step hydrothermal method. During the hydrothermal treatment, nanodisks and nanoflowers were formed by adding different polymers The morphology, microstructure and composition of the samples were characterized by field emission scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy.The XRD and FE-SEM results show that the AlN / Si piezoelectric The nanodisks, nanorods and nano-flower GZO formed on the substrate were wurtzite phases.The green fluorescent protein (GFP) was immobilized on the prepared GZO samples by impregnation method.GMA was analyzed by atomic force microscopy and fluorescence spectroscopy Its binding property with GZO surface was investigated and its feasibility for sensor and bioimaging was also investigated.The immobilization of trace GFP made the material have a fluorescence response, indicating that it has good activity when used in UV light sensor.
