The realization of white-light sources with a combination of high color rendering index (CRI), which is the average of the first eight rendering indices, and the deep-red color rendering R9 is an important challenge in the field of solid-state lighting. Herein, we report on a pure white hybrid light-emitting device combining a deep-blue emission from a polymer with blue, green, and red emissions from ternary CdSe/ZnS quantum dots. By carefully designing the device structure and tuning the ratio of QDs with different sizes, high CRI of 94 and R9 of 92 at 525 cd/m(2) were achieved.
实现显色指数（CRI）高的白光光源，其中 CRI 是前八个显色指数的平均值，以及显色指数 R9 深红光，是固态照明领域的一个重要挑战。在此，我们报告了一种纯白光混合发光器件，它结合了聚合物的深蓝色发射和三元 CdSe/ZnS 量子点的蓝色、绿色和红色发射。通过仔细设计器件结构和调整不同尺寸量子点的比例，在 525 cd/m(2) 时实现了高 CRI（94）和 R9（92）。
