Metallodielectric composites are very interesting from the point of view of metamaterials and plasmonics. Bottom-up methods, like self-organization and other chemical methods are potential future manufacturing techniques which could be suitable for large scale fabrication [1, 2, 3, 4].
The main idea of the work is to utilize the self-organization mechanism of metallodielectric eutectic materials to create plasmonic nanocomposites trough directional solidification.
In this work Bi2O3-Ag eutectic directionally solidified by the micro-pulling down method has been studied. The composite exhibits three-dimensional silver multiscale structure embedded in the bismuth oxide matrix. After applied annealing procedure in the Bi2O3-Ag composite the metallic nanoparticles are formed and material exhibits a localized surface plasmon resonance (LSPR) at around 590nm, which has been confirmed by the UV-VIS transmission spectra. This is the first demonstration of plasmonic behaviour in a eutectic which has been engineered specifically for this purpose using the self-organization mechanism.
The study of an influence of annealing temperature of the composite on the resonance properties in comparison with the pure bismuth oxide phase, together with micro/nano-structural investigation (XRD, SEM, TEM) will be presented. Additionally after doping the material with erbium ions, the enhancement of the luminescence at the telecommunication wavelength is observed.
