ZnO nanowire arrays decorated with titanium nitride nanoparticles as surface-enhanced Raman scattering substrates

In this work, the potential of ZnO nanowire arrays decorated with titanium nitride (TiN) nanoparticles as surface-enhanced Raman scattering (SERS) substrates is demonstrated. nanowires were grown by hydrothermal synthesis while commercially obtained TiN powders subjected to several hours mechanical grinding achieve 30–100 nm diameter nanoparticles. The then dispersed in acetone and drop cast on for decoration. Scanning electron microscopy confirmed presence nanowires. exhibited multiple absorption features at 430, 520 600 nm. SERS experiments using Nile blue methylene analyte molecules enhancement signals. It shown that origin effect chemical nature, contribution from different interactions between molecule current thus, represents a simple, cost-effective facile method fabrication TiN-based substrates.
