The optical responses, including electric field enhancement, absorption, reflection, and transmission spectra, were systematically investigated. Optimized geometrical parameters led to a significant enhancement of the electric field within the gap layers and almost perfect light absorptance for both structures. The results showed that the enhancement of the electric field depends on the polarization of the incident light. For both polarizations, the periodic circular nanodisk array showed a stronger field enhancement with an electric field enhancement factor of 6.6 × 106 and TE polarization, and a larger absorptance of 98% at its dipole resonance wavelength, indicating the fundamental plasmonic mode. In addition, weaker resonant modes were observed in the absorptance and reflectance spectra of both nanostructures, with the nanostrips exhibiting sharper and stronger higher-order modes, making them suitable for applications requiring precise wavelength selectivity and narrow-band responses. Despite their different geometric shapes, both structures exhibited similar optimized metal film thickness and nanoparticle height, comparable modes in number and position, and identical optimized light incidence angles. Furthermore, increasing the dielectric gap layer thickness and optimizing it to a specific value revealed its ability to measure the refractive index, making it a promising candidate for sensing applications.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"63 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the dispersion relationship, electric field distribution, absorptivity and other characteristics of the metal metasurfaces are obtained. The relationship between the thickness of the trace sample, the structural parameters of the device and the enhancement characteristics is investigated. The results demonstrate that the designed terahertz metallic metasurface exhibits high sensitivity and stability in detecting the absorption fingerprint spectrum of biomolecules. The absorption enhancement factor of the 0.1-μm thick α-lactose sample to be tested on the metallic metasurface is about 264 times higher than the direct absorption of terahertz waves by the untreated specimen.

Here, we synthesized Cu/Ni@rGO nanocomposite by using reduced graphene oxide (rGO) as a support which provided large surface area. A mixture of Cu and Ni nanoparticles (NPs) was embedded on its surface for sorption of heavy metal ions, i.e., Pb2+ and Cr6+, from binary mixture. Synthesis process of nanocomposite was monitored by UV-visible spectroscopy. FTIR analysis was performed to confirm the functional groups involved in synthesis and stabilization of the nanocomposite. The average size of nanocomposite was 26 nm calculated by XRD spectroscopy. SEM analysis revealed the thread-like structure of nanocomposite, while EDX gave information about elemental composition. Synthesized material was used to remove cations (Pb2+ and Cr6+) from binary mixture under tungsten lamp and without tungsten lamp. Under tungsten lamp, at 5 ppm concentration of binary mixture of cations, after 40 min of interaction with 10 mg adsorbent dosage at 45 °C temperature, 94% of cations was removed very efficiently. Thermodynamics studies showed that reaction of cations with nanocatalyst was spontaneous and exothermic in nature. Kinetics models were employed on experimental values and regression coefficient (R2) was near to unity (0.99) for pseudo 2nd order, which was considered the best fitted method for adsorption. Among sorption isotherms, the best fitted model was Freundlich isotherm as its R2 value (0.97) is near to unity. On these adsorption isotherms, error analysis was also applied to attain precision on results. Reusability of material was analyzed 5 times by desorption process which confirmed its stability and higher catalytic efficiency.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"54 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the impact of embedding the cluster of cubic plasmonic nanoparticles within the ultra-thin absorber layer of perovskite solar cells was investigated. Various types of metallic nanoparticles (including Au, Ag, Al, and Cu) were employed in the perovskite absorber layer, each with different thicknesses and widths. This facilitated a comprehensive comparison aimed at identifying the optimal structure for light absorption within the bandgap range of the perovskite absorber layer—specifically, 300 to 800 nm, corresponding to a bandgap energy of 1.55 eV. The layers used in the design of the perovskite solar cell in this research are SiO2/ITO/SnO2/MAPbI3/MoO3/Au. Optical and electrical analyses revealed that the local field intensity is significantly stronger at the edges of metallic nanoparticles. Notably, the efficiency of perovskite solar cells is enhanced by 56.87% (rising from 18.24 to 28.62%) with the incorporation of an Ag-based cluster of cubic nanoparticles, compared to perovskite solar cells without metallic nanoparticles. This achievement resulted in an overall efficiency of 28.62% and a short-circuit current of 31.22 mA/cm2. This result closely approaches the efficiency limitation of perovskite absorber layers, which indicates the potential for significant performance enhancements in future perovskite solar cell technologies.","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"15 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hemoglobin, a vital protein in red blood cells responsible for oxygen transport, serves as an important biomarker for numerous health conditions. Accurate and rapid measurement of hemoglobin levels can aid in the early detection and monitoring of anemia, blood disorders, and other medical conditions. This study presents a biosensor design for hemoglobin detection, integrating a graphene-based metasurface with circular and square ring resonators constructed from silver and gold nanostructures. The proposed sensor leverages the unique plasmonic properties of plasmonic nanostructures and the remarkable optical characteristics of graphene to enhance its performance. Extensive parametric analysis and optimization are conducted to enhance detection accuracy among other performance parameters. Detection analysis demonstrated the sensor’s ability to resolve changes in hemoglobin concentration through distinct shifts in transmittance and reflectance spectra. The resulting sensor exhibits enhanced sensitivity of 3500nmRIU−1 to infrared energy, maximum FOM of 17.6, and detection limits of 0.05 among other performance parameters. Furthermore, machine learning optimization using 1D convolutional neural network regression is employed to predict the sensor’s behavior achieving high accuracy with maximum R2 scores ranging up to 1.
