Electrically Driven Amplified Spontaneous Emission (ASE) from a Solution-Processed Colloidal-Quantum-Dot Device

Not Accessible

Your library or personal account may give you access

Abstract

By employing quantum dots with suppressed Auger recombination and a ‘current-focusing’ electroluminescent architecture with an integrated photonic waveguide, we realize for the first time ASE with a solution-processed optical gain medium (Nature 617, 79, 2023).
