Abstract：
Here we present comparative studies of: (i) the formation of ZnO thin films via the sol-gel method using zinc acetate dihydrate (ZAD), 2-methoxyethanol (ME) as solvent, and the aminoalcohols (AA): ethanolamine, (S)-(+)-2-amino-1-propanol, (S)-(+)-2-amino-3-methyl-1-butanol, 2-aminophenol, and aminobenzyl alcohol, and (ii) elemental analyses, infrared spectroscopy, X-ray diffraction, scanning electron microscopy, absorption and emission spectra of films obtained after deposition by drop coating on glass surface, and thermal treatments at 300, 400, 500 and 600 °C. The results obtained provide conclusive evidences of the influence of the AA used (aliphatic vs. aromatic) on the ink stability (prior to deposition), and on the composition, structures, morphologies, and properties of films after calcination, in particular, those due to the different substituents, H, Me, or iPr, and to the presence or the absence of a -CH2 unit. Aliphatic films, more stable and purer than aromatic ones, contained the ZnO wurtzite form for all annealing temperatures, while the cubic sphalerite (zinc-blende) form was also detected after using aromatic AAs. Films having frayed fibers or quartered layers or uniform yarns evolved to \"neuron-like\" patterns. UV and photoluminescence studies revealed that these AAs also affect the optical band gap, the structural defects, and photo-optical properties of the films.
摘要：
在这里，我们介绍了以下方面的比较研究：（i）使用二水合乙酸锌（ZAD）通过溶胶-凝胶法形成ZnO薄膜，2-甲氧基乙醇（ME）作为溶剂，和氨基醇（AA）：乙醇胺，(S)-(+)-2-氨基-1-丙醇,(S)-(+)-2-氨基-3-甲基-1-丁醇,2-氨基苯酚,和氨基苄醇，和（ii）元素分析，红外光谱,X射线衍射,扫描电子显微镜，通过滴涂在玻璃表面上沉积后获得的薄膜的吸收和发射光谱，以及300、400、500和600°C的热处理。获得的结果提供了所用AA影响的结论性证据(脂肪族与芳香)对油墨稳定性(沉积前)，在构图上，结构,形态学,以及煅烧后薄膜的性能，特别是,那些由于不同的取代基，H,我,或者iPr，以及-CH2单元的存在或不存在。脂肪膜,比芳香的更稳定更纯净，在所有退火温度下都含有ZnO纤锌矿形式，而立方闪锌矿（闪锌矿）形式也在使用芳香族AA后检测到。具有磨损的纤维或四分之一层或均匀纱线的薄膜演变为“神经元样”图案。紫外和光致发光研究表明，这些AA也影响光学带隙，结构缺陷,和薄膜的光学性能。
