Key Points

The research aims to explore how blend composition affects the morphology and exciton dynamics of polymer films.
Created a series of MEH-PPV:PMMA blend films with varying compositions.
Analyzed the morphology and exciton dynamics through systematic experimental techniques.
Compared properties of dilute dispersions to pristine MEH-PPV films.
Identified significant differences in morphology across the blend compositions.
Observed that these morphological variations impact exciton dynamics in the films.

Implication

Experimental analysis reveals morphology influences exciton dynamics in MEH-PPV:PMMA thin films, highlighting critical interactions.

Abstract

The interplay between morphology and exciton and polaron dynamics defines the photophysics of conjugated polymer blends. A systematic series of MEH-PPV:PMMA blend films, spanning from dilute dispersions to pristine MEH-PPV...
