TiZrV non-evaporable getter (NEG) coating is being developed at KEK for future light source applications. In order to understand influence of adsorbed gases on pumping performance, the coated films were characterized by thermal desorption spectroscopy, glow discharge optical emission spectroscopy and speed measurement. adsorb active gases, among these O2 pumped 6–7 times as many CO. After atmos...

ConspectusLanthanide ions are prime ingredients for the design of compounds, materials, and devices with unique magnetic optical properties. Accordingly, coordination chemistry is one best tools building molecular edifices from these because it allows careful control ions’ environment dimensionality final compound.In this Account, we review our results on lanthanide-based dimers. We show how a ...
