Abstract

In this study, we present an efficient method for fabricating surface-enhanced Raman scattering (SERS) substrates using ZnO@Au thin films, achieved through radio frequency magnetron sputtering followed by post-annealing process. The photo-induced enhanced Raman scattering (PIERS) effect was thoroughly evaluated through both experimental and simulation approaches. In-situ UV irradiation yielded a 4-fold increase in SERS intensity, enabling a thiram detection limit of 10^-9 M. The prepared substrates demonstrated exceptional reusability and durability, maintaining high performance over extended periods. The combination of experimental data with simulations provides a comprehensive understanding of the PIERS effect, highlighting the method’s potential for highly sensitive, reliable, and versatile analytical applications.

基于Au纳米粒子修饰ZnO薄膜的光致增强拉曼散射平台用于痕量分析物检测

在这项研究中，我们提出了一种利用ZnO@Au薄膜制造表面增强拉曼散射（SERS）衬底的有效方法，该方法通过射频磁控溅射和后退火工艺实现。通过实验和模拟两种方法对光致增强拉曼散射（PIERS）效应进行了全面的评价。原位紫外线照射使SERS强度增加了4倍，使其检测限为10-9 m。制备的底物表现出优异的可重复使用性和耐久性，在较长时间内保持高性能。实验数据与模拟的结合提供了对PIERS效应的全面理解，突出了该方法在高灵敏度、可靠和通用分析应用方面的潜力。

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
