Influence of Blend Composition on Morphology and Exciton-Charge Dynamics in MEH-PPV:PMMA Thin Films

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.
