WebNov 1, 2004 · On the other hands, o- and m-fluorophenethylammonium were asymmetrical configuration, and the polarization was increased. Therefore, the exciton peaks were shifted to the shorter wavelength. 4. ConclusionIn summary, we studied the effects of electronic state in the organic ammonium layers on the optical properties of two … Web2D perovskite single crystals have emerged as excellent optoelectronic materials owing to their unique anisotropic properties. However, growing large 2D perovskite single crystals remains challenging and time-consuming. Here, a new composition of lead-free 2D perovskite—4-fluorophenethylammonium bismuth iodide [ (F-PEA) 3 BiI 6] is reported.
