Here, we demonstrate deep-blue carbon dots (CDs) with luminescence centered at 415 nm and PLQY exceeding 60% nitrogen doping. A bright and high-color-purity CDs-based light-emitting diode (CLED) is achieved with an external quantum efficiency (EQE) of 1.74%, a maximum luminance of 1155.0 cd m, and a colour coordinate (0.16, 0.08) closely approaching the HDTV standard color Rec.BT.709 (0.15, 0.06) specification.
在这里，我们展示了具有 415nm 中心波长和超过 60%的磷光量子产率的深蓝色碳点（CDs），其具有氮掺杂。通过实现亮度为 1155.0 cd m 的最高亮度和接近 HDTV 标准颜色 Rec.BT.709（0.15，0.06）规范的色坐标（0.16，0.08），我们获得了一个基于明亮且高色纯度的碳点发光二极管（CLED），其外量子效率（EQE）为 1.74%。
