Photophysics, Photochemistry, and Electronic Properties of Alkalides and Electrides

这项更新建议侧重于研究碱、电子和混合体系的光学和电学性质，以确定晶体固体中电子-电子相互作用的性质，导致电子自旋配对的因素，以及金属-非金属转变的性质。将制备这些材料的薄膜、微晶膜和单晶，并研究它们的发射光谱、反射光谱、透射谱和荧光光谱。将测定粉末和单晶的电导率和阻抗谱，并研究它们的光电子和热电子发射。

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.
