(a) Photoluminescence (PL) and photoluminescence excitation (PLE) spectra of CsCu2Br3, (b) Time-resolved photoluminescence (TRPL) decay curve of CsCu2Br3. The experimental decay (symbols) is fitted with a bi-exponential model (solid line). The first column of the inset table lists the best-fit parameters (A1, A2, τ1, τ2), while the second column corresponds to their associated fitting errors (standard errors obtained from the regression).
