Presentation Title

Dipole Orientation and Strain-Enhanced Luminescence in Small Molecule Thin Films

Abstract

Organic light-emitting diodes (OLEDs) are widely considered as the promising light source to solve the energy issue to some extent, due to their high energy conversion efficiency and capability to cover large areas for general illumination. While most previous research focus on the OLED device with amorphous thin film, the orientation of small molecules in thin film and its effect on devices do not get enough attention until 2011. Phthalocyanines (Pc’s) are cost-effective and flexible electronics alternative for certain traditional silicon-based semiconductor applications. They exhibit high mobilities and long-range interactions due to the highly directional π-orbital overlap. Our previous research result show that the photoluminescence (PL) intensity increases as strain is applied to the thin film.
