Controlled two-dimensional distribution of nanoparticles by spin-coating method

Abstract

We demonstrate that the controlled distribution of nanoparticles can be achieved by employing the spin-coating method. The Co and Ag nanoparticles were uniformly distributed on the Si and SiO2 substrates with this method. The particle density was controllable by varying the concentration of colloids. The spatial distribution of the nanoparticles within the patterned area was also shown to be uniform with small boundary effect, which is favorable for current microelectronics technology. We propose that the spin-coating method can be utilized in developing mass production processes for future nanodevices.

Effect of Ag nanoparticles integrated within antireflection coatings for solar cells

“…11,12 The first method can be applied to solar cells by spin coating. 13,14 It has recently been proposed that the resulting material matrix incorporating Ag MNPs can be optimized as antireflective coating (ARC). 11,[15][16][17] This type of structure usually shows an aging of Ag PPL 18 and therefore some authors have proposed the addition of a protective layer to avoid the degradation.…”

Microfluidic patterning of nanoparticle monolayers

“…Solutions to obtain nanoparticle monolayer have mainly focused on evaporation approach and other non-evaporation methods, including dip-coating, lifting-up and spin-coating Dimitrov and Nagayama 1996;Kondo et al 1995;Horozov et al 2003;Yin et al 2001;Fan and Stebe 2004;Ogi et al 2007;Hong et al 2002). The traditional evaporation method is still the most prevalent way due to its intrinsic ability to keep the sample far from interferences to take full advantage of the self-assembly effect and close-packed monolayer can be easily achieved.…”

Direct Condensation Method for the Preparation of Organic‐Nanoparticle Dispersions

“…Spin-coating of nanoparticle dispersions allows variation of the surface coverage depending on the concentration of the dispersions. [28] Surface coverage ranging from a few single particles on the surface up to densely packed particle films could also be obtained by spinning our organic-nanoparticle dispersions on silicon substrates (Fig. 5).…”
