报告摘要：

Ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization. All ferroelectrics are pyroelectric 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 sensing of rare-earth doped piezo-ceramics on different circumstance conditionals, such as, compositional change, Curie temperature and electric polarization strength. Stress-luminescence on basis of piezo-electro-luminescence will also be showed. Ferroelectric materials possess the ability to convert vibration energy or cold-hot alternation thermal-energy into electric energy. I will also show my recent work related on some novel catalytic design such as piezo-catalysis and pyro-catalysis of ferroelectric micro-/nanomaterials, which is potential for application in dye wastewater degradation, water splitting into hydrogen, and carbon dioxide reduction through harvesting the environmental vibration energy or room-temperature cold-hot fluctuation thermal-energy.
