A sublimated film of double decker terbium(III) bis(phthalocyaninato) complex (TbPc2) has been tested for optical gas sensing applications. Morphological characterization of the sensing layer has been performed by atomic force microscopy. TbPc2 has been used as an opto-chemically interacting material to detect a class of volatile organic compounds (VOCs) following in real-time the UV–vis optical absorption...
In this work a fast, cheap and reproducible strategy for the realization of gold nanoparticles (NPs) over large areas is presented and their unique optical properties due to the excitation of Localized Surface Plasmon Resonances (LSPR) investigated. Based on thermal de-wetting of thin metal films, this fabrication method allows the realization of wafer-scale homogeneous distributions of gold nano-islands...
In this work, for the first time, Au nanostructures are investigated in a transverse magneto-optical (MO) configuration coupled to a Kretschmann experimental setup; a sizable MO activity can be recognized by using an external magnetic field of low intensity. Modelling tools are used to predict and realize a proper design of the investigated materials tailored on the nanoscale. Optical and morphological...
In this work we present a theoretical and experimental analysis of a new and cheaper plasmonic material, very attractive for its potential biosensing applications. We investigate the optical properties and the sensing capabilities of a highly disordered system of silica nanowires decorated with spherical gold nanoparticles. These systems present unique light trapping properties due to the combination...
