Sažetak
We considered theoretically and experimentally a stretegy to functionalize plasmonic metamaterials utilizing either metal-organic framework (MOF) or inorganic-organic hybrids for the application in adsorption-based gas sensing. MOFs are 1D, 2D or 3D crystalline compounds which simultaneously contain metal ions or ion slousters and organic moieties, forming thus porous networks ensuring increased effective surface for adsorption. Metamaterials can enhance plasmonic sensor performance through , etal-dielectric nanocompositing that simultaneously tailors the electromagnetic response and boosts adsorption of the target analyte through the use of nanpores. To performe functionalization, it is necessary to integrate one or several layers of MOF nanocrystals with the metamaterial scarffold. The simplest approach is to use dip or drop coating or layer-to-layer technique.The scarffolds that we considered included freestanding, ultrathin membranes and sandwich structures with nanoaperture arrays. For this investigation, we used a non-aqueous sol-gelroute to synthesize vanadium oxyanthracene carboxylate, a novel material with 1D crystal structure. Our results suggest that preferential concentration of analyte within the MOF pores may ensure improved adsorption and thus sensorsensitivity enhancement. Also, one may increase selectivity by introducing nanoparticle fillters or by utilizing other functionalizing materials like catalists or lignads.
