A Complete Inorganic Colour Converter Based on Quantum-Dot-Embedded Silicate Glasses for White Light-Emitting-Diodes

Abstract

A complete inorganic quantum dot color converter for a white LED is achieved using silicate-based quantum-dot-embedded glasses (QDEGs). The white LED exhibits a high CRI of 90 and highly improved thermal stability up to 200 degrees C, demonstrating its robustness and practicality. The CdSe/CdS core/shell structure within the silicate glass is expected to enhance the colour converting efficiency.
