Steady and transient state photoluminescence (PL) spectra  are measured using a 405 and 475 nm excitation wavelengths, respectively. PL decay curves of a the FAPbBr3 single crystal and b the FAPbI3 single crystal. c Comparison of carrier lifetimes of OIHPs single crystals (seven FAPbBr3 samples are tested)2729. d The correlations between carrier lifetimes and average single crystal growth rates (in volume) based on our work and literatures21,2628.
