“…Soda-lime and float glasses with their large commercial availability, high transparency, good chemical durability, high sodium content, and ion inter-diffusion coefficients are the most popular material for the realisation of SERS substrates by ion-exchange process. The presence in trace of some impurities, such as iron or arsenic, within these glasses promotes the reduction of the exchanged noble metal ions into metallic clusters during the subsequent sample treatment [100,[155][156][157][158].…”

Glasses, in their different forms and compositions, have special properties that are not found in other materials. The combination of transparency and hardness at room temperature, combined with a suitable mechanical strength and excellent chemical durability, makes this material indispensable for many applications in different technological fields (as, for instance, the optical fibres which constitute the physical carrier for high-speed communication networks as well as the transducer for a wide range of high-performance sensors). For its part, ion-exchange from molten salts is a well-established, low-cost technology capable of modifying the chemical-physical properties of glass. The synergy between ion-exchange and glass has always been a happy marriage, from its ancient historical background for the realisation of wonderful artefacts, to the discovery of novel and fascinating solutions for modern technology (e.g., integrated optics). Getting inspiration from some hot topics related to the application context of this technique, the goal of this critical review is to show how ion-exchange in glass, far from being an obsolete process, can still have an important impact in everyday life, both at a merely commercial level as well as at that of frontier research.

“…In particular, the optical properties of Ag NPs have been historically exploited in decorative pigments for jewellery/handicrafts, staining glass, or ceramics [ 26 , 27 , 28 , 29 ]. Over the last decades, Ag NPs have found use in many areas, such as catalysis [ 30 , 31 ], optical and electro-optical devices [ 23 , 32 ], surface-enhanced Raman spectroscopy (SERS) [ 33 , 34 ], and antimicrobial agents [ 14 , 35 ]. Ag NPs are promising nanofillers to obtain composites with electrical and optical properties to extend the applicability of SLA including the electronic or biomedical fields [ 13 , 14 , 36 , 37 , 38 , 39 ].…”

Synthesis of Silver Nanocomposites for Stereolithography: In Situ Formation of Nanoparticles

Additive Manufacturing (AM) offers remarkable advantages in relation to traditional methods used to obtain solid structures, such as the capability to obtain customized complex geometries adapted to individual requirements. The design of novel nanocomposites suitable for AM is an excellent strategy to widen the application field of these techniques. In this work, we report on the fabrication of metal/polymer nanocomposites with enhanced optical/electrical behaviour for stereolithography (SLA). In particular, we analyse the in situ generation of Ag nanoparticles (NPs) from Ag precursors (AgNO3 and AgClO4) within acrylic resins via SLA. Transmission electron microscopy (TEM) analysis confirmed the formation of Ag NPs smaller than 5 nm in all nanocomposites, providing optical activity to the materials. A high density of Ag NPs with a good distribution through the material for the larger concentration of AgClO4 precursor tested was observed, in contrast to the isolated agglomerations found when the precursor amount was reduced to 0.1%. A significant reduction in the electrical resistivity up to four orders of magnitude was found for this material compared to the unfilled resin. However, consumption of part of the photoinitiator in the formation process of the Ag NPs contributed to a reduction in the polymerization degree of the resin and, consequently, degraded the mechanical properties of the nanocomposites. Experiments with longer curing times showed that, for the higher AgClO4 concentrations tested, post-curing times of 300 min allowed an 80% degree of polymerization to be achieved. These conditions turned these materials into promising candidates to obtain solid structures with multifunctional properties.

“…5 A wide range of fabrication tools have been used to create bespoke plasmonic optical elements and coatings 6,7 but large-scale patterning suitable for industrial manufacture on low cost substrates, such as glass, is challenging, especially if robust coatings are required. Traditionally, the formation of plasmonic nanoparticles in glass has been performed either by ion-implantation, 8,9 which is expensive and can require subsequent annealing, or by ion-change in glass by thermal or electric-eldassisted methods, [10][11][12][13] which can be slow, difficult to pattern on small scales, or require elevated temperatures and molten salts. Hence, new methods to produce bespoke plasmonic patterns would be valuable.…”

Laser implantation of plasmonic nanostructures into glass

et al. 2013

A laser direct-writing method producing high-resolution patterns of gold, silver and alloy plasmonic nanoparticles implanted into the surface of glass substrates is demonstrated, by scanning a pulsed UV laser beam across selected areas of ultra-thin metal films. The nanoparticles are incorporated beneath the surface of the glass and hence the patterns are scratch-resistant. The physical mechanisms controlling the process are investigated and we demonstrate that this technique can be used to fabricate a wide range of plasmonic optical structures such as wavelength selected diffraction gratings and high-density substrates for lab-on-chip surface-enhanced Raman spectroscopy.
