报告摘要:Ferroelectricityis a characteristic of certain materials that have aspontaneouselectric polarization. All ferroelectrics arepyroelectric and all pyroelectrics are piezoelectric. Rare earth doping can not only help to enhance the ferro-/piezoelectric property, but also obtain excellent photoluminescence property. In this talk, I will demonstrate some experimental results on the photoluminescence sensitivity of rare-earth doped piezo-ceramics on different circumstance conditionals, such as, compositional change, Curie temperature and electric polarization strength. Some stress-luminescence performance on basis of piezo-electro-luminescence will also be showed. At last, I will show my recent work related on some novel catalytic design such as vibration-catalysis and pyro-catalysis of ferroelectric nanomaterials for application in dye wastewater degradation and water splitting into hydrogen.
