Q1: What is Formamidinium Lead Bromide (FAPbBr₃)?
Answer: Formamidinium Lead Bromide (FAPbBr₃) is a lead halide perovskite material, consisting of formamidinium (FA⁺), lead (Pb²⁺), and bromide (Br⁻) ions. It is widely used in optoelectronic devices like LEDs, solar cells, and photodetectors due to its excellent luminescent and electronic properties.
Q2: How does FAPbBr₃ differ from FAPbI₃?
Answer: FAPbBr₃ uses bromine (Br⁻) instead of iodine (I⁻) as the halide. As a result, FAPbBr₃ has a larger band gap (~2.2 eV) compared to FAPbI₃ (~1.48 eV), making it more suitable for emitting green light and for applications like LEDs. FAPbI₃, with a smaller band gap, is better for solar cell applications.
Q3: What is the significance of FAPbBr₃ in perovskite LEDs (PeLEDs)?
Answer: FAPbBr₃ is an important material in perovskite LEDs because it emits bright green light with high photoluminescence efficiency. Its optoelectronic properties make it an ideal candidate for energy-efficient, high-performance green LEDs.
