Blue‐Emitting ZnSe(Te) Quantum Dots and Light‐Emitting Diodes
Advanced Science, EarlyView.. ABSTRACT Zn‐based quantum dots (QDs) have been regarded as the most promising Cd‐free candidates for blue‐emitting applications. ZnSe QDs exhibit an ultra‐narrow full width at half maximum (FWHM), high photoluminescence quantum yield (PLQY), and excellent environmental stability, making them ideal for blue‐violet emitters.
