White color generation using blue top emission OLED and nanocrystalline materials

White light is of great technical interest in many photonic applications. This work developed colloidal solutions containing mutually immiscible green perovskite nanocrystals and red InP quantum dots as color conversion materials for generating white light. By combining our green/red color conversion materials and a top emission blue OLED as an excitation source, it was possible to generate white light with a range of color temperatures. Our technical approach can be extended to a wide variety of photonic applications where controllable color temperature is desirable. This article is protected by copyright. All rights reserved.
