Replacing a nitrogen heteroatom in a molecular Eu complex with a phenyl moiety facilitated sunlight-like emissions for sustainable white LEDs and non-contact thermometers

To enhance the quality of white light (mimicking sunlight-like emission) for solid-state lighting (SSL) applications, a novel imidazolyl-bipyridyl ligand was designed as an ancillary ligand to achieve multi-coloured emissions in a Eu( iii ) complex.
