Research data supporting “How to Characterize Emerging Luminescent Semiconductors with Unknown Photophysical Properties”

Figure 4b is of time resolved photoluminescence decay from a formamidinium-cesium lead iodide (Cs0.3FA0.7PbI3) halide perovskite following excitation at 470 nm at different incident laser powers, with experimental setup described in A. R. Bowman, S. D. Stranks, and B. Monserrat, Investigation of singlet fission–halide perovskite interfaces, Chem. Mater. 34, 4865 (2022). Figure 5a presents the scaling of initial counts with laser power for time resolved photoluminescence decays of methylammonium lead iodide and platinum octaethylporphyrin, using the experimental setup described in A. R. Bowman, S. Macpherson, A. Abfalterer, K. Frohna, S. Nagane, and S. D. Stranks, Extracting Decay-Rate Ratios from Photoluminescence Quantum Efficiency Measurements in Optoelectronic Semiconductors, Phys. Rev. Appl. 17, 044026 (2022). Figure 5b and c present the time resolved luminescence decay and scaling of initial counts with time between laser pulses of methylammonium lead iodide when using tine correlated single photon counting. Data for (b),(c) are generated using a 520 nm laser (PicoQuant LDH 400) pulse and recorded by a single-photon avalanche diode (LifeSpec – ps, Edinburgh Instruments).
