| Abstract | Various sizes and morphologies of noble metal/zinc oxide hybrid materials have promising applications in surface-enhanced Raman scattering (SERS). Generally, organic agents used during the synthesis of metal nanoparticles will inexorably induce organic pollution on the surface of SERS substrate, resulting in a negative effect on detection sensitivity. Herein, a stable and clean 3D flower-like ZnO/Ag hierarchical microstructure SERS substrate was designed and fabricated via a simple photocatalytic method. This synthetic strategy does not involve usage of any organic agents, which ensures the cleanness and free of impurities interferences. As anticipated, the as-fabricated 3D flower-like ZnO/Ag SERS substrates with high surface-to-volume ratio increased numerous hot spots, and exhibited excellent detection sensitivity to Rhodamine 6G. A linear relationship between the Raman intensity and the concentration of Rhodamine 6G ranging from 10−11 to 10−4 M was realised. This work demonstrated a performance-enhanced SERS sensor based on microflower-like ZnO@Ag hybrids, which provides a potential method to develop highly sensitive and stable SERS sensor for organic molecules detection. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
