title: Data for "Effect of luminescent nanocrystal alignment on fluorescence anisotropy and light guiding in polymer films"

description: DescriptionThis dataset accompanies the publication "Effect of Luminescent Nanocrystal Alignment on Fluorescence Anisotropy and Light Guiding in Polymer Films" and includes experimental data used to produce the figures in the article. The study investigates the optical properties of polymer films containing luminescent nanocrystals, focusing on changes induced by solvent casting and film stretching.This dataset includes:Absorbance and fluorescence spectraNanocrystal alignment and fluorescence anisotropy dataStrain measurementsPhotoluminescence quantum yield (PLQY), waveguiding, and internal photon efficiency (IPE) dataMonte Carlo simulation inputs and outputsPublication DetailsWhen using this data, please cite: Warner, T., Rinaudo, M., Xu, Y., Han, J., Ashokan, A., Kirkwood, N., Widmer-Cooper, A., Smith, T.
