“…It is important to note that the product arising from silica and alkali hydroxide followed by AgNO 3 addition is called Ag‐NP but is likely a combination of Ag‐NP and Ag 2 O aggregates. Similar absorption trends have recently been observed by Kipke and Hofmeister (42) during the formation of Ag 2 O in glass. They attribute a band redshifted from the Ag‐NP SPR band to silver oxide, which could be transformed into the Ag‐NP SPR band by annealing.…”

“…Future studies could be carried out to better understand Ag‐NP production through these means, which are attractive for large‐scale, simple and controllable production of Ag‐NP as we have shown. This lack of understanding and research regarding Ag 2 O nanoparticles on silica and related Ag‐NP formation has recently been acknowledged by Kipke and Hofmeister (42), and there is much room for future work to be done to explore the exciting possibilities in better understanding and utilizing this approach to Ag‐NP formation.…”

Silver nanoparticles (Ag-NP) on silica were produced in aqueous solution by deposition of silver on colloidal silica in a small cuvette using radiation from a xenon-mercury lamp. Ag-NP were also synthesized on a much larger scale with low-level, long-term visible light irradiation for several months. In both cases, the nanoparticle production was monitored by the appearance of the surface plasmon resonance (SPR) band at around 410 nm. The growth of the nanoparticles was directly related to the time exposed to radiation, which could be tracked spectrophotometrically over time. We also investigated the possibilities of rapid nanoparticle production without the assistance of radiation though silver oxide by adding alkali hydroxide, which is a relatively unexplored approach for syntheses of Ag-NP on silica. The SPR absorption of Ag-NP was used as a tool in evaluating the size and shape of the resulting nanoparticles along with dynamic light scattering and transmission electron microscopy data. In order to better utilize and understand Ag-NP, we present various ways to control their production through initial concentration adjustments, irradiation effects, gravitational fractionation, sonication and silver oxide formation.

“…A luminescence in the same spectral region was also found in Ag + -Na + ion exchanged glass [9,20,21]. Additionally, kinetic studies [22][23][24] in Ag + -Na + ion exchanged glass reveal a formation sequence with at least two colourless precursors of silver metal nanoparticles, which could also be related to the studied luminescence. Aim of this study is therefore a better understanding of this donor related luminescence.…”

“…A variety of methods have been used to prepare nanoparticles in oxide glasses, ranging from the standard annealing processes, or sol-gel preparation, over ion-exchange by diffusion, ion implantation, to irradiation with photon or particle beams [13][14][15][16][17][18][19][20][21][22]. Amongst the latter, laser irradiation [23,24] is the most established technique in particular for the precipitation of copper and silver nanoparticles in glass.…”

Nanoprecipitation in different oxide glasses by means of electron irradiation in transmission electron microscopy (TEM) has been compared in this study. Upon irradiation, groups or patterns of nanoparticles with various morphologies and sizes were formed in borosilicate glasses, loaded with zinc, copper, and silver. The study successfully includes loading ranges for the target metal from doping level (1%) over medium level (20%) to majority phase (60%). It is found that particle patterning resolution is affected by parallel processes of amorphous phase separation, glass ablation, and delocalised precipitation. In addition, via an in-situ study, it is confirmed that by heating alone without irradiation, no precipitate nanoparticles form.
