“…Enhanced Raman signal from a gold film adsorbed with mitoxantrone molecules deposited on silica colloidal photonic crystal surface is reported [138]. Raman signal is five times more than that from gold film deposited on a glass substrate under similar conditions [138].…”

“…In this way, Raman signal from molecules adsorbed on the surface can be enhanced by using photonic crystals as substrate. Instead of using a metallic film on the top of the colloidal film [138], colloidal crystal film can be itself made of metallic spheres as given in Ref. [139] and such silver-coated colloids are used to enhance the Raman signal.…”

“…In addition to direct enhancement of Raman signal, nanotextured noble metal substrates offer drastic quenching of otherwise competitive or even dominating fluorescence thus increasing Raman-based detectibility of pigments [23][24][25]. In the recent years, several noble metal nanostructures have been proposed as SERS active substrates [26][27][28][29].…”

Enhanced Raman Scattering of Ultramarine on Au-coated Ge/Si-nanostructures

et al. 2011

Semiconductor self-assembled Ge-on-Si quantum dot structures coated with Au film were successfully employed as surface-enhanced Raman scattering (SERS) substrates to characterize ultramarine blue inorganic art pigment. To assign the bands and to reveal the enhancement mechanisms, the quantum-chemical calculations of vibration spectra of linear and cyclic model compound of SiO 4 and AlO 4 tetrahedra were carried out. The overtones are observed in the SERS spectra and the unharmonicity constants were estimated. The development of a series of new bands in SERS spectra of ultramarine are discussed in terms of electro-optical unharmonicity.

“…Usually a thermal vacuum deposition of noble metals (gold or silver) on either lithographic 13,14 or self-organized 15 templates is used to develop nanostructured metal films. Many authors proposed vacuum deposition of metal film combined with subsequent thermal annealing in air.…”

Plasmon-enhanced fluorescence of labeled biomolecules on top of a silver sol-gel film

et al. 2012

A simple chemical technique was devised for the fabrication of silver nanostructured substrates which can be used for plasmonic enhancement of labeled proteins fluorescence. For bovine serum albumin labeled with fluorescein isothiocyanate, the obtained enhancement factor ranges from three to seven, depending on metal-luminophore spacing and silver nanoparticle size. For excitation with linear polarized light, the enhancement factor increases noticeably for p-polarization and decreases for s-polarization. The experimental results were interpreted in terms of the theoretical model in which the enhancement factor depends on incident light polarization, luminophoremetal spacing and silver nanoparticle size. Proposed plasmonic substrates can be considered as an affordable replacement of standard ones in different types of fluorescent assays for the purpose of increasing sensitivity.
