[OLED4-5L] Solution-Processed Indium-Gallium-Nitride (InGaN) Blue Light-Emitting Diodes (LEDs)

*TADAHIKO HIRAI1, TETSUO TSUCHIYA2 (1. CSIRO (Australia), 2. AIST (Japan))

Keywords:InGaN, Light Emitting Diode (LED), Organic LED (OLED), Quantum Dots (QDs), Blue

A soluble form of InGaN was synthesized, producing a solution that exhibited blue photo-luminescence (PL) upon UV light exposure. This solution was used in the fabrication of a blue light-emitting diode (LED) that was produced using solution processable methods, a world first for an InGaN-base LED. The PL properties of the solution and the electro-luminescence (EL) and device characteristics of the LED are presented.
