The hydrothermal synthesis and morphology-dependent properties of flower-shaped ZnO microstructures have been extensively described in this study. The growth of flower-shaped ZnO microstructures has been conducted in HMT aqueous solutions containing zinc nitrate tetrahydrate precursor in three different hydrothermal temperatures (100 °C, 150 °C, and 200 °C). Morphological observations and structural analysis have been performed using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transfer infrared spectroscopy (FT-IR), and Raman spectroscopy. Morphological studies have indicated a transition from sheet-like petals to rod-like structures for flower-shaped architectures with the increase of reaction temperatures. XRD patterns have revealed single-crystalline behavior for as-synthesized ZnO microstructures. Crystalline quantities have been investigated using a variety of X-ray line broadening analysis techniques including Debye-Scherrer and Williamson-Hall methods. UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS) has been employed to carry out the optical studies and estimate optical band gap energies. The optical results have suggested morphology-dependent responses for flower-shaped ZnO microstructures.

花状ZnO微观结构的水热合成和形态依赖的性质已被广泛描述。在三种不同的水热温度（100°C，150°C和200°C）中，在含有硝酸锌四水合物前体的HMT水溶液中进行了花形ZnO微结构的生长。使用场发射扫描电子显微镜（FESEM），X射线衍射（XRD），傅立叶转移红外光谱（FT-IR）和拉曼光谱进行了形态学观察和结构分析。形态学研究表明，随着反应温度的升高，花形建筑从片状花瓣过渡到杆状结构。XRD图谱显示了合成后的ZnO微结构的单晶行为。已使用多种X射线线展宽分析技术（包括Debye-Scherrer和Williamson-Hall方法）研究了结晶量。UV-Vis漫反射光谱法（UV-Vis DRS）已被用于进行光学研究和估计光学带隙能量。光学结果表明花形ZnO微结构的形态依赖响应。
