In this work, for the first time, the chain-like ethylammonium (EA) [(C2H5)NH3]+ caiton as an alternative cation was introduced into FAPbBr3 cubic crystals to form the mixed-cation FAxEA(1-x)PbBr3 perovskite nanowires (NWs). The results indicate that the incorporation of chain-like EA cation contributes to the inertial growth of nanowires along c axis. Replacing FA with EA can realize bandgap tuning and morphology transformation between cubic shape and nanowires. Similarly, suitable chain-like EA cation doping in MAPbBr3 can also result in the growth of nanorods. The tuned band gap of perovskite is attributed to the variation of Pb-Br-Pb angles induced by the insertion of larger EA cation.
