Project description
The development of new light-emitting materials is essential for many fields of sustainable technology as these can be used for making make novel light-emitting diodes (LEDs) and thin-film transistors (TFTs). Introducing gold atoms in organometallic frameworks can yield new kinds of light-emitting materials. Gold nanoclusters surrounded by phosphine ligands are another promising material for these tasks. In this project, the effects of structural modifications on the optical properties of these materials will be investigated using novel methods that enable an accurate description of electronic transitions of the molecules. The radiative part of the transitions give rise to light emission. Since gold is expensive and relatively rare, copper or silver can in some cases be used. Light emission properties of new mixed coinage-metal complexes containing copper or silver and gold will be investigated with the aim to find molecules with good emission, enabling more sustainable technology.
