In the last few decades, ultrasound assisted methods have emerged as environmentally friendly and cost-effective technologies for chemical synthesis. It provides higher yields under mild reaction conditions compared to traditional methods. Methyl ammonium lead iodide and zinc oxide have gained importance in academic as well as industrial research due to their unique optoelectronic properties. Ultrasonication induces changes in the material properties due to acoustic cavitation in the solvent based synthetic approach. As a proof of the concept, the present work includes the study of impact of ultrasound treatment on optical and morphological properties of the title compounds. All the products were characterized by using various analytical techniques such as DRUV, PL, FTIR, XRD and FE-SEM-EDS. XRD reveals the formation of pure phase of the products. Optical properties are analyzed using DRUV and PL spectroscopy and Tauc‘s plot. Surface modification is observed in both the products (ZnO and methyl ammonium lead iodide) synthesized by sono assisted method inducing changes in the optical band gap. Interestingly, ZnO shows increase in particle size because of ultrasound impact leading to decrease in photocatalytic activity.

在过去的几十年中，超声辅助方法已成为环境友好且具有成本效益的化学合成技术。与传统方法相比，它在温和的反应条件下提供更高的产率。甲基铵碘化铅和氧化锌由于其独特的光电特性而在学术和工业研究中获得了重要地位。由于基于溶剂的合成方法中的声空化作用，超声处理会引起材料特性的变化。作为这一概念的证明，目前的工作包括研究超声处理对标题化合物的光学和形态特性的影响。所有产品均采用DRUV、PL、FTIR、XRD和FE-SEM-EDS等多种分析技术进行表征。XRD揭示了产物的纯相的形成。使用 DRUV 和 PL 光谱以及 Tauc 曲线分析光学特性。在通过声波辅助方法合成的两种产物（ZnO 和甲基铵碘化铅）中都观察到了表面改性，从而导致了光学带隙的变化。有趣的是，由于超声影响导致光催化活性降低，ZnO 的粒径增加。
