Bismuth based novel substrate for surface enhanced Raman spectroscopy

Exploring the potential of non-noble metal substrates for Surface-enhanced Raman spectroscopy (SERS) has attracted considerable interest in recent years. In this work, we prepared nanoplate beta-Bi2O3/Bi2O2CO3 heterostructure via calcination of Bi2O2CO3 precursor using a facile hydrothermal process and successfully demonstrated its use as a novel SERS substrate. The SERS sensitivity of substrate was performed by probing methyl orange (MO), rhodamine B (RhB), vitamin C (Vit. C), and melamine. The observed results show that the SERS signal is enhanced considerably by the adsorption of probe molecules on the surface of the Bismuth heterostructure SERS substrate.

Automated summary

This study explores the potential of non-noble metal substrates for Surface-enhanced Raman spectroscopy (SERS) and prepares a nanoplate beta-Bi2O3/Bi2O2CO3 heterostructure as a novel SERS substrate. The results demonstrate that the SERS signal on this substrate is significantly enhanced by adsorbed probe molecules.
