From: Quantitative optical assessment of photonic and electronic properties in halide perovskite
Experimental results obtained with the multidimensional imaging methods. a PL profiles for each emitted photon energy from 1.52 eV to 1.68 eV. The PL regime, where electronic diffusion dominate, appears in blue. The photon propagation regime, where photonic regime dominate, appears in green. b PL spectra at increasing distances from the laser spot. The inset shows IPL spectrum at r = 8 µm as the sum of a locally emitted and a propagated contribution. c PL profiles at incremental time steps after the laser excitation. d Time-resolved PL decay at the center, and at r = 2 µm, both normalized at t = 0 ns
