Enhancing White Light-Emitting Diode Performance with Ultra-Wide Spectrum ZnS:Mn-CDs@SiO2 Dual Core@Shell Composite
Recent progress in the field of carbon dots (CDs) has highlighted their significant potential, attributed to their exceptional optical properties and diverse applications, most notably in the realm of white light-emitting diodes (WLEDs). CDs are recognized for their broad spectrum of emission, adjustable fluorescence, and excellent thermal stability, making them ideal candidates for use in WLEDs. However, the challenge lies in synthesizing CDs that can emit long-wavelength, multicolor light from a single host material. This research presents a highly efficient dual-core-shell structured white-emitting phosphor, denoted as ZnS:Mn-CDs@SiO2, which has achieved an impressive photoluminescence quantum yield (PLQY) of 25.8% and an expansive full width at half maximum (FWHM) of 131 nm. The successful implementation of this novel material has led to the creation of WLEDs with Commission Internationale de l'Eclairage (CIE) coordinates at (0.32, 0.38) and a correlated color temperature (CCT) of 5856 K, marking a significant stride in the development of high-performance WLEDs.
