讲座内容简介：Colour in metallic solids is an unusual property that has been prized since ancient times in jewellery applications. Among over 100,000 intermetallic compounds reported in the literature, only ~100 exhibit colour.Most coloured intermetallics crystallize in high-symmetry structures (CsCl- or Cu2MnAl-type), have relatively simple stoichiometries (1:1, 1:1:1, 1:1:2), and possess energy gaps along special directions in their electronic structures. Recently we have synthesized Cu2LiM (M = Ga, Al) compounds showing golden yellow and pink colours, and characterized them by X-ray diffraction and solid-state NMR spectroscopy. Expanding on these efforts to discover other candidates for coloured intermetallics, we are now systematically evaluating the detailed electronic structures of many compounds to identify the common features that are likely to give rise to colour.
