formamidinium lead bromide, perovskite light-emitting diodes, spin-coating, electroluminescence, PEDOT: PSS


Formamidinium bromide (FABr) was synthesized by slowly mixing formamidinium acetate powder with hydrobromic acid for synthesizing FAPbBr\(_3\). Photoluminescence (PL) of~FAPbBr, has been studied, showing a PL peak at 562 nm. Spin-coating method was used to prepare FAPbBr\(_{3}\) thin films and FTO/FAPbBr/FTO sandwich structures. These structures exhibited green luminescence with a center wavelength at 545 nm. The emission centers were observed for single crystals of FAPbBr\(_3\) perovskite.
