Absorption, PL, PLQY, and time-resolved PL of the perovskite film. a Optical absorption and b PL for the perovskite films without (solid lines) or with (dashed lines) crown for different PEABr ratios. c PLQY (excited at 365 nm at approximately 2.3 mW cm−2) versus PEABr ratio for the perovskite with and without crown. d Time dependence of PL intensity for the perovskite films with 0% PEABr (red), 40% PEABr (blue), and 40% PEABr-crown (black)
