Contains 1 zip file within which there are 20 csv or xlsx datasets as follows: Fig_1b and Fig_1c contain steady-state absorption and photoluminescence measurements (x-axis wavelength in nm, y-axis counts), Fig_1d contains normalised transient photoluminescence data (x-axis time in s, y-axis counts) of TTM-3PCz and CMA-CF3 molecular emitters. Fig_2a is the complete 2D transient absorption dataset from which exciton dynamics in 3% TTM-3PCz in CMA-CF3 blend are studied (x-axis time in s, y-axis probe wavelength in nm, z-axis deltaT/T signal). Fig_2b contains spectra extracted from the same 2D dataset (x-axis wavelength in nm, y-axis counts). Fig_2c contains populations of excited states extracted from several 2D TA datasets (x-axis time in s, y-axis counts).
Fig_3 contains temperature dependent transient photoluminescence measurements within which a series is the blend and b series is pristine CMA-CF3; and Main (x-axis time in us, y-axis counts) and Inset presents the same data but integrated (x-axis time in s, y-axis normalised integrated counts). Temperatures labelled in K.
Fig_4b contains the EQE curve of the OLED device (x-axis current density in mA/cm2, y-axis EQE), Fig_4c contains current density vs. voltage and radiance vs. voltage data, Fig_4d contains electroluminescence spectra at several voltages.QG is grateful to the Cambridge Trust and China Scholarship Council (GrantNo.201808060075) for the financial support.
