Sobre IBD

Des frustules siliceuses ont été extraites d’une espèce représentative de diatomées d’eau douce (Cyclotella sp.) par traitement à l’acide chlorhydrique (HCl) aqueux. Les caractéristiques structurelles des frustules nettoyées ont été examinées au microscope électronique à balayage (MEB). Les images microscopiques ont montré que les diatomées ont une forme circulaire régulière et sont de taille presque identique (longueur moyenne de 9 μm et largeur moyenne de 3 μm). Il a été observé que les frustules étaient principalement composées de silice (~87 % en atomes) et d’oxydes métalliques (~11,5 % en atomes), comme l’ont montré les mesures FT-IR et EDX. L’émission optique a montré des bandes claires à 440 et 375 nm, qui proviennent des microstructures de silice de 200 nm. Des dispositifs photoniques peuvent être fabriqués à partir de cette nanostructure naturelle.
