Silver nanoclusters formation in ion-exchanged glasses by thermal annealing, UV-laser and X-ray irradiation

Influence of pulsed laser irradiation on precipitation of silver nanoparticles in glass

“…Therefore various microstructures are created when the laser pulse is focused into transparent materials due to multiphoton processes. A number of experimental works with pulsed Nd:YAG laser irradiation concern metal polymer nanostructures, photochromic glasses, optical waveguides which all consist in the ion-exchange process in soda lime glasses [13][14][15][16].…”

High confinement ion-exchanged waveguides for nonlinear applications

“…We therefore analyze the damage thresholds as follows: light is absorbed by silver particles, which in the case of high peak power, locally heat the glass, thus causing irreversible damages. Moreover, it has been shown elsewhere [24] that the UV-laser irradiation induces the formation of silver nanoclusters. Therefore, we also assume that the system absorbance is increased during the waveguides damage leading to a runaway mechanism.…”

Surface plasmon resonance in nano-gold antimony glass–ceramic dichroic nanocomposites: One-step synthesis and enhanced fluorescence application

“…Composite materials synthesized by metal clusters embedded in glass matrices have occupied a very unique position in materials science since the millennia due to their striking optical and electronic properties [1][2][3][4][5]. Consequently they are widely used for optoelectronic applications, as part of all-photonic devices, optical communications, switching and sensing devices [1,6].…”

“…Fabrication metal-glass and metal-glass-ceramic nanocomposites by conventional techniques are not simple and involves intricate multi-step pathways like ion-implantation, ionexchange, melting at high temperatures with small quantity of reducing agents, photosensitive nucleating agents, and then subsequent laser, ion or X-ray bean irradiation and long time heat treatment in reducing atmosphere (H 2 ), UV-light /Co gradiation to precipitate and grow the metal nanoparticles [1][2][3][4][5]. Moreover, dichroic glasses are generally produced by deformation of embedded spherical NPs into ellipsoidal NPs by intense irradiation with ultrashort laser pulses [13][14][15].…”
