Abstract:

White-light emission has evoked great attention as one of the most promising technologies in the applications of solid-state lighting devices, light emitting diodes, and flat-panel displays. However, up to now, pure white-light emitting materials have rarely been reported. Here, we present a single-component white-light emitting semiconductor, [C5H9-NH3]4CdBr6, which exhibits CIE chromaticity coordinates of (0.33, 0.33). Notably, this value is the same as that of the standard pure white-light emission. Remarkably, it shows an ultrahigh color rendering index of 92.5, which exceeds that of mixed-phosphor light sources and is comparable to the recently reported highest one among single-component materials. Mechanistic studies indicate that the white-light emission originates from the synergetic effect of deep defects coupled with the organic component. Such an organic-inorganic hybrid with outstanding color characteristics will pave a new approach in the development of white-light emitting materials with practical applications. © 2017 The Royal Society of Chemistry.
