Abstract
A novel blue excitable green fluorescent triazine-based material with high thermal stability (up to 350 °C) has been synthesized. Solid-state structural characterizations showed bright solid-state photoluminescence centered at 490 nm with an internal quantum yield (iQY) up to 40%. The coordination capabilities offered by the presence of a multi nitrogen and oxygen heteroatom framework allows to use TABNO (4,4′,4′′,4′′′-((6,6′-oxybis(1,3,5-triazine-6,4,2-triyl))tetrakis(azanediyl))tetrabenzonitrile) as Tb3+ and Eu3+ photosensitizer, thus delivering a purely organic host matrix for Ln ions with tunable light emissions. Blending this new material with K2SiF6:Mn4+ allowed access to a new class of REE free NUV-blue excitable warm light-emitting phosphors.
