An organic–inorganic hybrid ferroelectric with strong luminescence and high Curie temperature
2020
Coexistence of ferroelectricity and luminescence in a material makes it a very interesting multifunctional material for fabricating new optoelectronic devices. As a single-component system with flexibility and structure tunability, the organic-inorganic hybrid luminescent ferroelectrics are more attractive than the previous reported rare-earth-doped ones. We herein report a new organic-inorganic hybrid ferroelectric, (C10H16N)2MnBr4, which exhibits ferroelectricity with Curie temperature of 421 K and green-light emission with a high photoluminescence quantum yield (PL QY) of 88.52%. Furthermore, it shows excellent film-forming ability. The thin film with high quality can be easily prepared by spin-coating method. These advantages endows it great potential application in optoelectronic devices.
