Research data supporting Singlet Fission Luminescent Solar Concentrators

Data contains Photographs, Mathematica code and Origin files for the modelling and plots within the paper. UV–vis-NIRabsorption spectra were measured using a Shimadzu UV-3600Plus dualbeam spectrometer. The diluted solution samples were measured usingquartz cuvettes (Hellma) with a reference sample of neat solvent. Samples wereexcited with a pulsed supercontinuum laser (Fianum Whitelase SC-400-4, 6 ps pulse length) at 0.2 MHz repetition rate. The pump wavelengthset to either 535 or 650 nm (full-width at half-maximum 10 nm) withdielectric filters (Thorlabs). Pump scatter from the laser excitationwithin the photoluminescence path to the detector was filtered-outwith an absorptive 900 nm long-pass filter (Thorlabs). The infraredphotoluminescence was focused and detected by a single-photon avalanchephotodiode based on InGaAs/InP (MPD-InGaAs-SPAD). Thelongtime (ns-μs) transient absorption setup has been describedpreviously. In short the pump–probesetup consists of a probe from a LEUKOS Disco 1 UV supercontinuumlaser (STM-1-UV, 1 kHz) and a pump generated in a TOPAS optical amplifierpumped with the output from a SpectraPhysics Solstice Ace Ti:sapphireamplifier (1 kHz). The probe beam is split into a reference and probeand both are focused onto the sample. A pair of line image sensors(Hamamatsu, G11608) mounted on a spectrograph (Andor Solis, Shamrock SR-303i) is used to detect the signal using a custom-built boardfrom Stresing Entwickslungsburo to read out the signal.
