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.

用于磷光体转换 LED 技术的新型三嗪基 NUV 蓝光可激发材料的合成与表征

已经合成了一种具有高热稳定性（高达 350°C）的新型蓝色可激发绿色荧光三嗪基材料。固态结构表征显示出以 490 nm 为中心的明亮固态光致发光，内部量子产率 (iQY) 高达 40%。多氮和氧杂原子框架的存在提供的配位能力允许使用 TABNO (4,4',4'',4'''-((6,6'-oxybis(1,3,5-triazine -6,4,2-triyl))tetrakis(azanediyl))tetrabenzonitrile) 作为 Tb ³⁺和 Eu ³⁺光敏剂，从而为具有可调光发射的 Ln 离子提供纯有机主体基质。将这种新材料与 K ₂ SiF ₆ :Mn ^{4+ 混合} 允许获得一类新的不含 REE 的 NUV 蓝色可激发暖光发光荧光粉。
