Abstract:Valon vuorovaikutus metallinanohiukkasten kanssa määräytyy metallin vapaiden elektronien ominaisuuksista. Nanohiukkaseen kohdistettu valo saattaa rakenteen elektronit voimakkaaseen kollektiiviseen värähtelyyn muodostaen niin kutsutun paikallisen pintaplasmonin. Hiukkasen koko, muoto ja koostumus sekä sitä ympäröivä muu aine vaikuttavat tämän plasmonivärähtelyn ominaistaajuuteen ja voimakkuuteen. Tällaisia plasmonien ominaisuuksia voidaan hyödyntää nanoteknologian sovelluksissa kuten auringonvalon energian kohdentamisessa, spektroskopisissa havaintolaitteissa ja lääketieteen menetelmissä. |
