The paper is dedicated to the recently developed by the authors technique of silver nanoisland growth, allowing self-arrangement of 2D-patterns of nanoislands. The technique employs silver out-diffusion from ion-exchanged glass in the course of annealing in hydrogen. To modify the silver ion distribution in the exchanged soda-lime glass we included the thermal poling of the ion-exchanged glass with a profiled electrode as an intermediate stage of the process. The resulting consequence consists of three steps: (i) during the ion exchange of the glass in the AgxNa1−xNO3(x= 0.01–0.15) melt we enrich the subsurface layer of the glass with silver ions; (ii) under the thermal poling, the electric field displaces these ions deeper into the glass under the 2D profiled anodic electrode, the displacement is smaller under the hollows in the electrode where the intensity of the field is minimal; (iii) annealing in a reducing atmosphere of hydrogen results in silver out-diffusion only in the regions corresponding to the electrode hollows, as a result silver forms nanoislands following the shape of the electrode. Varying the electrode and mode of processing allows governing the nanoisland size distribution and self-arrangement of the isolated single nanoislands, pairs, triples or groups of several nanoislands—so-called plasmonic molecules.

AbstractThe fractures of a soda-lime glass surface layer were investigated under irradiation by a high-power ion beam of nanosecond duration with different current densities. Two kinds of cracks (perpendicular and approximately parallel irradiated surfaces) have been identified. It is defined that cracks approximately parallel to the surface are localized at a depth of 10 ± 2 µm from the irradiated glass surface after one-time irradiation with a current density of 100 A/cm2. The formation of these cracks was detected within ~170 h after the end of irradiation when irradiated samples were under an air atmosphere. In a vacuum, the growth of these cracks was insignificant. It is shown that irradiation of heated glass or heating of glass started no later than 2–3 min after irradiation can suppress or substantially reduce surface fracture of glass. The possible mechanisms of glass fracture were discussed.

Existing methods for the microfabrication of convex structures on a glass surface require a complex and expensive masking process. In this study, a simple microfabrication method that combines the masking process using polyimide tapes and a micro-slurry jet (MSJ) process was developed. The masking process was performed using a CO₂ laser machine, and the surface of the processed glass was observed using a three-dimensional laser microscope. Although the geometric shape of the mask was not a perfect circle, convex structures with a diameter of approximately 1.0 mm and heights of more than 1.5 μm were formed on soda-lime glass surfaces. The deepest structures were observed to create convex structures with a height of 19 µm. The effects of the travel speed of the nozzle and number of repetitions of the MSJ process on the height of the convex structures on the glass surface were also investigated. It was found that the masking process combining polyimide tapes and the MSJ process could form high-convexity structures on the glass surface. The proposed method is expected to enable the fabrication of devices with various functional properties for materials that cannot be processed using existing methods.

This study reports the laser grooving of glass. In this study, an ultraviolet (UV) nanosecond laser is used to produce grooves in soda lime glass by varying laser power, scan speed, pulse repetition rate, and number of scans. The threshold power density to generate damage on glass surface is found to be ~6.37 × 108 W/cm2. According to the result of a single laser scan, at a high laser power and low scan speed, material removal does not nearly occur, and only volume melting underneath the glass surface and large thermal crack are induced. With the decreasing laser power and increasing scan speed, a groove with a smooth surface is formed owing to the melting-dominant material removal process. The groove of rough surface morphology is produced with the further increase of the scan speed due to shattering induced by shock wave. Under this condition, it is found that either small cracks are produced or a crack-free groove is obtained. In this study, the fabrication of the microchannel for bio-chip application is also attempted by multiple laser scans. The near rectangular-shaped and crack-free groove (width × depth: ~220 μm × ~500 μm) with quite a smooth surface is fabricated by the multiple laser scans with a non-zero scan spacing.

Weathering Resistance

The soda bloom - white stain on the glass surface – is an issue concerned in the glass manufacturing. It is because of high humidity and warm weather especially in the tropical region. The aim of this study was to modify glass batch to increase the weathering resistance for soda-lime glass. The weathering resistance of glass was measured by using the sodium (Na) leach technique according to the ISO 719. In principle, the strength of glass structure decreases with increasing Na content. The reactions start when free Na+ions moving to the glass surface and react with moisture from the surroundings. From this reason, the soda bloom occurs during storage lifetime. Two samples of glasses as described in Table 1 were modified with dolomite (CaMg (CO3)2) or alumina (Al2O3) to reduce the sodium free ion on the glass surface and increase the strength of glass structure Table 1: The glasses compositions All glasses were melted at 1500oC for 3 hours and annealed at 570°C. In glass structure, magnesium (Mg) and aluminium (Al) are network modifiers that can improve the structural strength and the weathering resistance of glass. The weathering resistance is in the inverse relationship with the weight of Na2O in mg per 50 ml of water according to theISO 719. The results showed that the weathering resistance increased with increasing dolomite or alumina contents. The experiments of increasing dolomite from 0 to 18 wt.% in a replacement of calcite showed the result that indicated the weight of Na2O in mg per 50 ml of water decreased from 0.53 to 0.41 mg, and the glass with increasing alumina from 0 to 1 wt.% showed that the weight of Na2O in mg per 50 ml of water decreased from 0.80 to 0.39 mg. According to the weathering chamber test under the cyclic atmospheric conditions of 60% and 80% relative humidity, and the cyclic temperatures of 20°C and 32 °C for 14 days, the glasses with more than 12 wt.% dolomite or more than 1 wt.% alumina did not generate the white stains on the surface. This process can be applied in the glass production. The satisfied result was found in the glass sample with 12 wt.% dolomite and 1 wt.% alumina. The weight of Na2O per 50 ml H2O reduced to 0.43 and 0.41mg, respectively, and the storage time increased from 3 months to 6 months without soda bloom.
