“…The PL spectrum for the dot produced by one pulse can be decomposed as a sum of two Gaussian spectral functions centered at ≈521 and 626 nm (denoted as P 1 and P 2 , respectively), which was assigned to the emission from Ag 2 clusters and Ag 3 clusters, respectively, and was similar to the emission behavior of clusters generated by thermal annealing or 10 7 pulses of UFL in the photosensitive glass. [ 3,30,31,34,35 ] Both P 1 and P 2 exhibited a red shift with an increase in the number of pulses, as shown in Figure S2, Supporting Information. This may have occurred because of an increase in the cluster size or the aggregation of clusters.…”

Directly controlling the clustering process in transparent solids is an effective way to tune the properties of clusters and is important for integrated devices. Herein, single‐pulse ultrafast laser (UFL) micromachining is conducted as a facile technique to engineer the ultrafast clustering of metal in glass. Stable Ag clusters with few atoms are generated without thermal activation and exhibit efficient emission. Consequently, the clustering efficiency is enhanced by more than a thousand times compared with that of previous studies. The photoluminescence (PL) intensity and diameter of the emissive dots are precisely tailored by adjusting the number of pulses, pulse energy, and Ag doping concentration. It is confirmed that single‐pulse UFL micromachining is significantly superior in creating submicrometer luminescent structures compared with multipulse writing. High‐capacity optical information storage with a high signal‐to‐noise ratio is demonstrated by directly writing Ag clusters in 3D. Single‐pulse UFL micromachining enables precise fine tuning of the local chemistry of transparent solids and opens perspectives for the construction of functional micro/nanostructures and devices in 3D with a high throughput.

Silver nanostructures, including molecular clusters and plasmonic nanoparticles, attract much attention due to their unique optical properties and potential applications in various fields. Glasses doped with silver molecular clusters are known to possess bright luminescence under UV excitation, which opens up prospects of using the glasses as solar spectral converters to overcome poor spectral response for most of photovoltaic cells in the short‐wavelength region. In this study, silver molecular clusters are formed in photo‐thermo‐refractive glass matrix both by UV irradiation and by Na+↔Ag+ ion exchange and optically characterized. Photo‐thermo‐refractive glasses doped with silver molecular clusters, independently on silver introduction method, are shown to demonstrate broad absorption in the UV, intense white emission under excitation at 360 nm, and high photoluminescence quantum yield that meet requirements for luminescence downshifting materials. Despite this, only photo‐thermo‐refractive glass with silver molecular clusters uniformly distributed in the glass volume enhances the output power of a silicon photovoltaic cell, thus showing the potential for future application of photo‐thermo‐refractive glasses in photovoltaics, particularly in case of further experiments.

“…Antimony oxide based glasses have been the subject of interesting studies in the last years [1][2][3][4][5][6][7][8][9][10][11] and have been claimed to be useful in important fields of the materials science, such as photonics [12][13][14][15][16] and plasmonics [17][18][19] . These materials present low phonon energy (~600-700 cm -1 ) due to low energy stretching vibrations of Sb-O-Sb band 20,21 , high linear and nonlinear refractive indexes [3][4][5] and the possibility of modulation of their optical constants, (refractive index, n, and absorption coefficient, ) under laser irradiation 22 what make them promising materials for 3D optical storage 23,24 as well as, for holographic data storage 25 .…”

(x) , with composition 0.1  x  0.5 (in mol %) were studied. The structural changes due to the replacement of Sb 2 O 3 by WO 3 have been investigated. It was found that the incorporation of WO 3 enhances the thermal stability of the glasses against devitrification when compared to the binary Sb 2 O 3(0.6) -SbPO 4(0.4) composition. The connectivity of the network increases with WO 3 content which is consistent with the high values of the glass transition temperature. Raman studies suggest that WO 3 incorporation breaks the primary network, constituted by antimony oxide, while a second network containing WO 6 octahedral units is built up. Thermal and structural properties were evaluated by differential scanning calorimetry, infrared and Raman spectroscopies, 31 P Magic Angle Spinning NMR and X-ray absorption near edge structure (XANES) at L 1 and L 3 edges of Sb and L 1 edge of W atoms.
