Temperature Dependent Interplay Between Emitting Species in Highly Ordered P3ht Single Crystals

Agumba O. John

In this study, the temperature dependent photoluminescence (PL) spectra measurement has provided us a feasible means to elucidate the nature of the emissive species and the melt transitions in P3HT single crystals. This has been achieved by performing in situ temperature dependent photoluminescence measurements followed by detailed spectral analysis. Spectrally resolved PL lineshapes through multipeak Gaussian functions simulating 0-0, 0-1, 0-n peaks have revealed multiple vibrational replicas yielding two and three emitting species (states) between 30
