Composition-Tunable Formamidinium Lead Mixed Halide Perovskites via Solvent-Free Mechanochemical Synthesis: Decoding the Pb Environments Using Solid-State NMR Spectroscopy
Download2018-01-01
Askar, A.M., Karmakar, A., Bernard, G.M., Ha, M., Terskikh, V.V., Wiltshire, B.D., Patel, S., Fleet, J., Shankar, K., Michaelis, V.K.
Mixed-halide lead perovskites are becoming of paramount interest in the optoelectronic and photovoltaic research fields, offering band gap tunability, improved efficiency, and enhanced stability compared to their single halide counterparts. Formamidinium-based mixed halide perovskites (FA-MHPs)...
