Tuning Excimer Concentrations While adding Quantum Dot and Phosphor Conversion Layers to Improve Efficiency, Lifetime, and Color Quality of Blue Light in Organic Light Emitting Diodes

This project investigated methods of efficiently replicating white light by emitting blue light as a primary light source and adding targeted wavelengths of amber light as a secondary source. The goal was to produce an OLED with a full visible light spectrum and high Color Rendering Index (CRI) by having the secondary source absorb high-frequency light and re-emit it at lower frequencies. The research team first produced primary light by altering the electron blocking layer and dopant concentration within the OLED. Secondary sources were then tested by adding a layer of either phosphor or quantum dots to the OLED surface.
