VUV-induced radiation ageing processes in CsI photocathodes studied by microscopy and spectroscopy techniques

Pranav Garg

CsI thin film photocathodes of 600 nm thickness deposited on polished Al surfaces by resistive evaporation technique were studied by angle-resolved X-ray photoelectron spectroscopy (ARXPS), before and after UV-irradiation under vacuum. It is shown that the ...

Structural, Spectroscopic, and Thermodynamic Consequences of Anti-Chelate Effect in Nine-Coordinate Lanthanide Podates

Jean-Claude Bünzli, Frédéric Gumy

The connection of three tridentate 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine binding units to an extended sulfurcontaining tripodal anchor in the ligand L9 yields nine-coordinate podates [Ln(L9)]3+ upon reaction with trivalent lanthanides, Ln(III). Struct ...
