Pure white hybrid light-emitting device with color rendering index higher than 90

Abstract

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. (C) 2010 Optical Society of America
