Artificial light plays an essential role in information technologies such as optical telecommunications, data storage, security features, and the display of information. Here, we show a chiral lanthanide lumino-glass with extra-large circularly polarized luminescence (CPL) for advanced photonic security device applications. The chiral lanthanide glass is composed of a europium complex with the chiral (+)-3-(trifluoroacetyl)camphor ligand and the achiral glass promoter tris(2,6-dimethoxyphenyl)phosphine oxide ligand. The glass phase transition behavior of the Eu(III) complex is characterized using differential scanning calorimetry. The transparent amorphous glass shows CPL with extra-large dissymmetry factor of g_CPL = 1.2. The brightness of the lumino-glass is one thousand times larger than that of Eu(III) luminophores embedded in polymer films of the same thickness at a Eu(III) concentration of 1 mM. The application of the chiral lanthanide lumino-glass in an advanced security paint is demonstrated.

人造光在光通信、数据存储、安全功能和信息显示等信息技术中起着至关重要的作用。在这里，我们展示了一种用于高级光子安全设备应用的具有超大圆偏振发光 (CPL) 的手性镧系元素发光玻璃。手性镧系玻璃由带有手性(+)-3-(三氟乙酰基)樟脑配体和非手性玻璃助剂三(2,6-二甲氧基苯基)氧化膦配体的铕络合物组成。使用差示扫描量热法表征 Eu(III) 络合物的玻璃相变行为。透明非晶玻璃显示出具有超大不对称因子g CPL的_CPL = 1.2。在 Eu(III) 浓度为 1 mM 时，发光玻璃的亮度是嵌入相同厚度聚合物薄膜中的 Eu(III) 发光体的一千倍。展示了手性镧系元素发光玻璃在高级防伪涂料中的应用。
