20.500.12556/RUL-171642 Priprava zlatih nanoploščic in njihovo združevanje s srebrnimi nanoploščicami Preparation of Gold Nanoplatelets and Their Combination with Silver Nanoplatelets Zlate nanoploščice spadajo pod nanomateriale, kar pomeni, da imajo vsaj eno dimenzijo manjšo od 100 nm. Koloidi zlatih nanodelcev izgledajo drugače kot bi pričakovali zaradi lokalizirane površinske plazmonske resonance, saj se njihova barva namesto zlate giblje med rdečo in modro. Pri rdeči barvi pričakujemo več sferičnih delcev, pri modri pa več ploščičastih. Zlate nanoploščice nastanejo zaradi dvojčične napake na {1,1,1} ploskvi. Raziskovali smo sintezne poti in različne reducente, da bi dosegli čim večji delež nanoploščic. Medtem ko je literatura navajala najvišje izkoristke pri sintezi z jodidnimi ioni in askorbinsko kislino, je edini postopek, pri katerem nam je uspelo doseči nezanemarljivo količino ploščic, sinteza inducirana s svetlobo. Poskusili smo združevati zlate nanoploščice s srebrnimi, pa nam to ni uspelo. Gold nanoplatelets are a type of nanomaterial, which means, that at least one of their dimensions is smaller than 100 nm. Colloids of gold nanoparticles appear different than what we would expect because of localised surface plasmon resonance, as their color is between red and blue instead of gold. With red color, we expect more spherical particles and with blue color more plate-like particles. Gold nanoplates form because of a twinning defect on the {1,1,1} facet. We explored the possible synthesis paths and different reducing agents with the goal of achieving the highest possible yield of nanoplatelets. While literature described the highest yield at the synthesis with iodide ions and ascorbic acid, the only process, that produced a non-negligible yieldn of nanoplates was light-induced synthesis. We also attempted to combine gold nanoplates with silver nanoplates, which was unsuccessful. zlate nanoploščice srebrne nanoploščice lokalizirana površinska plazmonska resonanca koloid. gold nanoplates silver nanoplates localised surface plasmon resonance. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-08-29 10:00:00 2025-08-29 10:00:07 2025-09-12 09:01:43 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 25744 248701699 Gadour_sentjurc_Idris_-_Priprava_zlatih_nanoploscic_in_njihovo_zdruzevanje_s_srebrnimi_nanoplosc.pdf Gadour_sentjurc_Idris_-_Priprava_zlatih_nanoploscic_in_njihovo_zdruzevanje_s_srebrnimi_nanoplosc.pdf 1 8A5A96C854ADDCF84EE46907ACE217A5 d02f00eba71fbeee4f907f02d5791c02dfa14d22d66c4decb7454169113c8d4c 0d5ffeef-84ae-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215022 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
