In this study, a white light emitting nanocomposite was constructed by chemically coupling halide perovskite nanocrystals with a metal quinolate complex. The coupling process did not affect the morphology, size, and dopant oxidation state of the nanocrystals, while providing additional environmental stability. The resulting nanocomposite exhibited bright white light emission properties close to those of midday sunlight.
Herein we report the construction of a white light emitting (WLE) nanocomposite by chemically coupling halide perovskite nanocrystals (HPNCs; e.g., orange-emitting Mn2+-doped CsPbCl3) with a metal quinolate complex (e.g., a cyan-emitting calcium quinolate (CaQ(2)) complex) while keeping their distinct features. The surface chloride of HPNCs coupled with the Ca-metal center of the CaQ(2) complex without altering the morphology, size, and dopant oxidation state of the HPNCs and provided additional environmental stability of the WLE nanocomposite. The photostable solid WLE nanocomposite displays chromaticity of (0.33, 0.32), color rendering index (CRI) of 80, correlated color temperature (CCT) of 5483 K, and quantum yield of 54.1%. This clearly indicates their bright WLE nature with properties close to those of bright midday sunlight. The current work will bring new surface chemistry between HPNCs and inorganic complexes and new paradigm toward advanced light emitting applications.
