Tuvu sakārtotu metāla nanodaļiņu masīvu optisko īpašību izmantošana sensoru veidošanai

subject

description

Darbā tiek pētītas tuvu sakārtotu metāla nanodaļiņu masīvu, iegūtu ar anodizeta oksīda maskas palīdzību, īpašības. Sudraba un zelta nanodaļiņas ar diametru 20-30 nm robežās un centru attālumu 50 nm izrāda spēcīgu gaismas izkliedi redzamajā un tuvajā infrasarkanajā reģionā lokalizētās plazmonu rezonanses dēļ. Pateicoties masīvu tuvajai sakārtotībai var novērot haotisku granulu struktūras interferences ainu izkliedētajā gaismā, kura ir atkarīga no polarizācijas un citiem eksperimentāliem parametriem. Darba galvenais uzdevums ir pētīt šo masīvu optiskās īpašības un to pielietojumu sensoru izgatavošanai. Svarīgākais rezultāts ir novērotā polarizācijas maiņa izkliedētajai gaismai daļiņu mijiedarbības dēļ, kā arī demonstrēts laušanas koeficienta noteikšanas sensors, kurš balstās uz izkliedētās gaismas depolarizāciju
