White-light emitting multi-lanthanide terephthalate thin films by atomic/molecular layer deposition

Abstract

Precisely composition-tuned white-light-emissive lanthanide-organic thin films are fabricated using the combined atomic/molecular layer deposition (ALD/MLD) technique. The emission colour characteristics are comparable (and even exceeding) those measured for commercial incandescent...

Atomic/molecular layer deposition of europium–organic thin films on nanoplasmonic structures towards FRET-based applications

“…In recent years, several new ALD/MLD processes for luminescent Ln–organic thin films have been developed. 34–39 In these films the excitation wavelength range has been found to depend on the choice of the organic component, but has nevertheless remained relatively narrow. 40,41 In this study, we introduce a new organic precursor, 2-hydroxyquinoline-4-carboxylic acid (HQA), which allows us to significantly extend the excitation energy range towards the longer wavelengths.…”

Tunable emissions in lanthanide-based supramolecular metallogels

“…25 These white light-emitting materials can be generated by adjusting the blue, green, and red light-emitting components, which often results from the coordination of lanthanide ions to suitable hosts or ligands. 26–29 For example, studies on lanthanide-based luminescent gels by Gunnlaugsson, Maji, and co-workers 30–32 discussed low molecular weight gelators that showed various material properties, including tunable luminescence, and white light emission. These strategies have been proposed to achieve white luminescence.…”
