The First Organic-Inorganic Hybrid Luminescent Multiferroic: (Pyrrolidinium)MnBr3

A hybrid organic-inorganic compound, (pyrrolidinium) MnBr3, distinguished from rare earth (RE)-doped inorganic perovskites, is discovered as a new member of the ferroelectrics family, having excellent luminescent properties and relatively large spontaneous polarization of 6 mu C cm(-2), as well as a weak ferromagnetism at about 2.4 K. With a quantum yield of >28% and emission lifetime >0.1 ms, such multiferroic photoluminescence is a suitable candidate for future applications in luminescence materials, photovoltaics, and magneto-optoelectronic devices.
