Abstract
One significant application of this research article is enhancing the sensitivity of refractive index-based localized surface plasmon resonance (LSPR) sensor by using TiN nanostructures. The LSPR-based sensors are highly effective in detecting minute environmental changes and a crucial measure for these sensors is the refractive index sensitivity (RIS). The unique properties of TiN nanoparticles and the precision of the FDTD method drive significant interest in optimizing size and shape of TiN nanoparticles for enhanced RIS. By optimizing above mention parameters, we maximized the RIS to ~979 nm/RIU, thereby improving the performance of LSPR-based sensors. This research is vital for developing highly sensitive and efficient nitride-based LSPR-based sensors, which have applications in biomedical diagnostics, environmental monitoring, and other fields.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
