20.500.12556/RUL-144324 Simple and tailorable synthesis of silver nanoplates in gram quantities Due to plasmonic and catalytic properties, silver nanoplates are of significant interest; therefore, their simple preparation in gram quantities is required. Preferably, the method is seedless, consists of few reagents, enables preparation of silver nanoplates with desired optical properties in high concentration, is scalable, and allows their long-term storage. The developed method is based on silver nitrate, sodium borohydride, polyvinylpyrrolidone, and H$_2$O$_2$ as the main reagents, while antifoam A204 is implemented to achieve better product quality on a larger scale. The effect of each component was evaluated and optimized. Solution volumes from 3 to 450 mL and concentrations of silver nanoplates from 0.88 to 4.8 g/L were tested. Their size was tailored from 25 nm to 8 μm simply by H$_2$O$_2$ addition, covering the entire visible plasmon spectra and beyond. They can be dried and spontaneously dispersed after at least one month of storage in the dark without any change in plasmonic properties. Their potential use in modern art was demonstrated by drying silver colloids on different surfaces in the presence of reagents or purified, resulting in a variety of colors but, more importantly, patterns of varying complexity, from simple multi-coffee-rings structures to dendritic forms and complex multilevel Sierpiński triangle fractals. silver nanoplates large-scale seedless synthesis high concentration plasmonic properties surface patterns colloids metal nanoparticles nanoplates silver surface plasmon resonance srebrne nanoploščice veliko merilo sinteza brez jeder visoka koncentracija plazmonske lastnosti površinski vzorci true false true Angleški jezik Slovenski jezik Članek v reviji 2023-02-14 14:26:42 2023-02-14 14:26:43 2023-02-15 03:41:00 0000-00-00 00:00:00 2023 0 0 Str. 2760-2772 iss. 2 Vol. 8 17 Jan. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.3:546.57 2470-1343 10.1021/acsomega.2c07452 137365251 acsomega.2c07452.pdf acsomega.2c07452.pdf 1 CE412AF024CF3B2A66577A373F3EA663 4e5a64ffc3758df77694a63d35a8da34898a75a604fdca446690445693d4f213 2e83f4c7-ac6b-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=166575 https://pubs.acs.org/doi/10.1021/acsomega.2c07452 1 e63acd51-ac6a-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=166574 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
