White‐Color Generation Using Blue Top‐Emission Organic Light‐Emitting Diode and Nanocrystalline Materials.

White light is of great technical interest in many photonic applications. In this work, colloidal solutions containing mutually immiscible green perovskite nanocrystals and red InP quantum dots are developed as color‐conversion (CC) materials for generating white light. By combining the green/red CC materials and a blue top‐emission organic light‐emitting diode as an excitation source, it is possible to generate white light with a range of color temperatures (CTs). The technical approach can be extended to a wide variety of photonic applications where controllable CT is desirable. [ABSTRACT FROM AUTHOR]
