title: Integration of CuInS2-based nanocrystals for high efficiency and high colour rendering white light-emitting diodes.
abstract: Here we explored the possibility of using CuInS2-based nanocrystals as colour converting materials for light-emitting applications. Using a mixture of red and green emissive CuInS2-based nanocrystals, we successfully fabricated high colour rendering white light-emitting diodes with surface mounted devices and high-power types. The devices exhibit improved luminous efficiency, high colour rendering index and tunable colour temperature. In particular, the low-power surface mounted devices have a luminous efficiency of ~70 lm W(-1), CRI of ~95 and tunable colour temperature of 4600-5600 K, which makes the CuInS2-based nanocrystals promising candidates for commercial applications.
