The improvement of the color rendering index using convex-dual-layer remote phosphor geometry with YOCl:Eu3

[...]attaining the blue-emitting FCDs is regarded as one of the crucial priorities in the development of lighting devices that can address optical shortcomings such as limited color range and inadequate chroma rendering index (CRI). PREPARATION The main phosphor we apply in this study is YOCl:Eu3+. Because of its rhombohedral (matlockite) structure, this phosphor is hygroscopic and must be stored in a dry environment. [...]selecting the concentration of YOCL: [...]as shown in previous studies, the luminous intensity (LI) of the increasing-CRI WLEDs may confront a minor drawback, which should be aware when being introduced to manufacturing. Because of red phosphor's ability to absorb light, the results of YOCL:
