“…We used an in-house TMM code for multilayer thin films (see the Computational Methods section for details). [36] We excited the structure in the so-called Kretschmann configuration, widely used for the surface plasmon resonance detection, with a plane wave incident through SiO 2 under a certain incident angle, potentially creating a surface plasmon resonance at the interfaces between ZrN and the adjacent dielectrics (predominantly at the air-ZrN interface). [37] Figure 4 shows the ZrN reflection and absorption heat maps, in comparison with the same setup with an Au layer.…”

Finding new plasmonic materials with prominent optical properties and unique physical and chemical characteristics, which are merits of traditional gold and silver, is of great interest to many applications. This work uses a series of powerful numerical methods, such as density functional theory (DFT) and electromagnetic modeling approaches, to predict the plasmonic response of a mechanically well‐known material, zirconium nitride (ZrN). DFT first delivers an electronic analysis and optical dispersion data between 1 and 8 eV, experimentally verified in the lower energy regime (), and extremely valuable for any subsequent optical modeling. Subsequent electromagnetic modeling steps, including the transfer matrix method (TMM) and Mie theory, demonstrate the excitation of surface plasmon polaritons and localized surface plasmon resonances in ZrN thin films and nanoparticles. Furthermore, the finite‐difference time‐domain (FDTD) method exhibits the excitation of distinct electric (plasmon) and magnetic (LC) resonances in a periodic array of u‐shaped ZrN split‐ring resonators (SRRs). The findings showcase an optical behavior comparable with structures made from noble metals such as gold and silver and support the introduction of ZrN as a new and appropriate candidate for plasmonic applications, specifically in technological applications where optical and mechanical properties are of simultaneous concern.

“…As an example, ultrathin 2D nanomaterials, especially single-layer nanosheets, where interlayer interactions are absent or limited, prepare the media suitable for unique electrical properties compared to other nanomaterials [42]. They also possess exceptional properties, due to their finite bandgap, superior flexibility, absence of dangling bonds, and significant resistance to short channel effects, which all could suggest a new generation of smart electronic, optoelectronic, and energy devices [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59], where the first two promise the modern generation of sensors and biosensors and the last one offers developed, long lasting batteries, and energy devices. In addition, 2D layered nanomaterials are advantageous for gas sensing application specifically due to their large surface area, which facilitates surface reactions [60].…”

“…This resonance angle can be increased by increasing the refractive index of the sensing layer caused by the binding of the Ni(II) ion. The WinSpall software was used throughout this study to characterize sample properties such as thickness and the refractive index of the thin film [49][50][51][52][53][54].…”

A novel vanadium–cellulose composite thin film-based on angular interrogation surface plasmon resonance (SPR) sensor for ppb-level detection of Ni(II) ion was developed. Experimental results show that the sensor has a linear response to the Ni(II) ion concentrations in the range of 2–50 ppb with a determination coefficient (R2) of 0.9910. This SPR sensor can attain a maximum sensitivity (0.068° ppb−1), binding affinity constant (1.819 × 106 M−1), detection accuracy (0.3034 degree−1), and signal-to-noise-ratio (0.0276) for Ni(II) ion detection. The optical properties of thin-film targeting Ni(II) ions in different concentrations were obtained by fitting the SPR reflectance curves using the WinSpall program. All in all, the proposed Au/MPA/V–CNCs–CTA thin-film-based surface plasmon resonance sensor exhibits better sensing performance than the previous film-based sensor and demonstrates a wide and promising technology candidate for environmental monitoring applications in the future.
