Fig. 1: Synthesis and characterizations of α-ETP2SbCl5.
From: Recyclable luminescent solar concentrator from lead-free perovskite derivative
a Synthesis scheme for α-ETP2SbCl5; b SEM images (scale bars = 10 μm), c XRD profile, and d Crystal structure of the α-ETP2SbCl5; e DFT calculated energy band structures and corresponding DOS profiles of α-ETP2SbCl5. The purple and green regions represent the distributions of CBM and VBM, respectively; f PLE (purple) and PL (yellow) spectra of as-synthesized α-ETP2SbCl5. The λem and λex are 600 and 365 nm, respectively. The dashed line represents the theoretical PL spectrum; g 365 nm-excited TRPL spectra of α-ETP2SbCl5 within 0–30 μs; Fitting results for (h) Eb, (i) S and ħω parameters
