As three-dimensional (3D) nanostructures can significantly improve the absorption capacity of photons, it is widely used in various photovoltaic devices. However, the high-cost and complex preparation process of traditional 3D nanostructures restricted its development greatly. In this paper, a new type of nanocone cluster microstructure was prepared on polydimethylsiloxane (PDMS) substrate by using a simple template process. This novel nanocone cluster microstructure can significantly improve the light transmittance and reduce the light reflection, showing superior anti-reflection property. In the whole range of visible band, the nanocone cluster microstructure effectively reduces the reflectivity of the light, so that it remains below 3.5%. In addition, this kind of cluster microstructure showed excellent superhydrophobic property and self-cleaning ability with the contact angle of 151°.

“…In principle, particles can be also heated by a rather weak laser energy absorption, or by the heat exchange with the surrounding liquid. These effects commonly lead to particle reshaping or even fragmentation (Antipov et al 2012;Makarov 2013). This process can become particularly important if liquid is heated up to a supercritical state (Abramov et al 2014).…”

“…The glass substrate was placed in the mixed solution. The deposition of thin film was made by laser irradiation as described by Antipov et al (2012). Here, we used Yb-fiber laser (k = 1.06 lm) with pulse duration of 100 ns and with laser repetition rate of 20 kHz.…”

International audienceWe report the results of continuous wave laser interactions with both gold and silver targets in the presence of different liquids (deionized water, ethanol, and glycerol). Upon moderate laser irradiation at wavelength of 1.06 nm during 30 min, nanoparticle colloids are shown to be formed with surprisingly narrow size distributions and average dispersion as small as 15–20 nm. The average particle sizes range between 8 and 52 nm for gold and between 20 and 107 nm for silver. This parameter is shown to be stable and well-controlled by such laser parameters as intensity and effective irradiation time, as well as by the choice of the liquid phase. The possibilities of an efficient control over the proposed synthesis techniques are discussed, and the results of a bimetallic Au–Ag structure deposition from the obtained colloids are presented. The formation of the extended arrays of gold and silver nanoparticles with controlled morphology is examined. The changes in the optical properties of the obtained thin films are found to depend on their morphology, in particular, on the particle size, and distance between them

“…When the mixture is heated to 600 ∘ K, the estimated diffusion coefficient ∼ 10 −10 cm 2 s −1 for nanoparticles with = 10nm in water. We note that this value corresponds only to the diffusion coefficient in the laser-heated volume, whereas is as small as 10 −18 cm 2 s −1 close of the substrate surface [12]. The proposed deposition method allows one to change the morphology of the deposited structures depending on the laser exposure conditions.…”

“…Our previous estimations have shown that nanoparticle temperature in the colloids reaches ∼600 K for a single laser passage [12]. With an increase in the number of laser passages, heat accumulation typically takes place leading to the laserinduced convection and thermal diffusion ensuring nanoparticle motion toward the substrate surface.…”

Moving nanosecond laser system is used for laser-assisted thermodiffusion deposition of metallic nanoparticles from water-based colloidal solutions. The results obtained for both gold and silver nanoparticles show that film morphology strongly depends on laser scanning speed and the number of passages. We show, furthermore, the possibility of producing bimetallic Au:Ag thin films by laser irradiation of the mixed solutions. As a result of several laser scans, granular nanometric films are found to grow with a well-controlled composition, thickness, and morphology. By changing laser scanning parameters, film morphology can be varied from island structures to quasi-periodic arrays. The optical properties of the deposited structures are found to depend on the film composition, thickness, and mean separation between the particles. The transparency spectra of the deposited films are shown to be defined by their morphology.
