Blue light-emitting polymer/dielectric nanolayer nanocomposites: Impediment of excimer formation and enhancement of photostability

Abstract

Blue light-emitting polymer/dielectric nanolayer nanocomposites were fabricated by solution intercalation method and the photoluminescence data showed that these nanolayers act as sepaxation layers to isolate polymer chains. Furthermore the dielectric nanolayers whose aspect ratio is about 500, also acted as efficient barriers to oxygen resulting in low keto-type emission and photo-oxidation.
