Abstract

We present a study of charge transfer and carrier dynamics in nano-films of zinc phthalocyanine (ZnPc) and buckmisnster¬fullerene (C60) by investigated by time-resolved terahertz spectroscopy (TRTS). We compare terahertz photocon¬ductivity dynamics in composite and multi-layered films of C60 and ZnPc. The few picosecond terahertz photoconductivity dynamics arise from autoionization and recombination between C60 molecules and cooling of hot photocarriers following from charge transfer between C60 and ZnPc.
