摘要
Magnet-optical materials embracing coupled magnetic and photoluminescent properties in single phase are promising in microelectronics and optoelectronic devices.However,the current research mainly focuses on traditional inorganic materials,and there are few reports on molecule materials.Recently,we synthesized an organic–inorganic hybrid complex((C_(6)H_(5)C_(2)H_(3)FNH_(3))_(2)MnCl_(4)(1)with perovskite structure.Physical measurements show that 1 not only behaves as an antiferromagnet with spin canting but also exhibits unusual fluorescent properties.Importantly,under the magnetic field at different temperatures,the luminous intensity of 1 changed,and a red-shift occurred with obviously optical hysteresis.These phenomena directly prove the existence of magneto-optical coupling in 1.More interestingly,the optical hysteresis can be observed in both low and high field,which is unprecedented in other molecular materials.Even in traditional inorganic materials,it can only be observed in strong field.This special function provides the possibility for the application of low energy consumption optoelectronic devices.
