tailieunhanh - Fabrication for formamidinium lead bromide perovskite for light emission

Formamidinium bromide (FABr) was synthesized by slowly mixing formamidinium acetate powder with hydrobromic acid for synthesizing FAPbBr3. Photoluminescence (PL) of FAPbBr, has been studied, showing a PL peak at 562 nm. Spin-coating method was used to prepare FAPbBr3 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 FAPbBr3 perovskite. |
