Photophysics, Photochemistry, and Electronic Properties of Alkalides and Electrides

这一更新提案的重点是研究碱化物、电子和混合系统的光学和电子性质，以确定具有弱捕获电子的晶体固体中电子-电子相互作用的性质，导致电子自旋配对的因素，以及金属-非金属跃迁的性质。将制备这些材料的薄膜、微晶薄膜和单晶，并对其发射光谱、反射光谱、透射光谱和荧光光谱进行研究。测定粉末和单晶的电导率和阻抗谱，并研究其光电子和热离子电子发射。

This renewal proposal focuses on a study of the optical and electronic properties of alkalides, electrides and mixed systems to determine the nature of electron-electron interactions in crystalline solids with weakly trapped electrons, factors which lead to electron spin pairing, and the nature of metal-non metal transitions. Thin films, microcrystalline films, and single crystals of these materials will be prepared, and their emission-, reflectance-, transmission-, and fluorescence-spectra studied. The electrical conductivity and impedance spectroscopy of powders and single crystals will be determined, and their photoelectron and thermionic electron emission investigated.
