Optical Properties of Polymer-Based Photonic Nanocomposite Materials

摘要: Designing metallodielectric nanocomposite materials for photonic applications implies the ability to reliably model and predict effect of metallic inclusions on optical properties a microstructured composite material. We present detailed analysis block copolymer based, multilayered Bragg reflectors discuss implications nanosize-specific effects design applications. A series lamellar poly(styrene-b-ethylene/propylene) thin films with varying filling fraction gold nanocrystals preferentially but randomly distributed within poly(styrene) domains have been studied by reflectometry. The reflective are compared calculations based effective medium concepts taking into account confinement dielectric function nanocrystals. particle size causes strong alterations in metal that relevance fo...
