Multi-layered CdSe/ZnS/CdSe heteronanocrystals to generate and tune white light
In this study, tuneable white light generation by controlling CdSe/ZnS/CdSe core/shell/shell heteronanocrystals integrated on InGaN/GaN light emitting diodes was presented. These multilayered quantum dots, also known as ...
InGaN/GaN based LEDs with electroluminescence in violet, blue, and green tuned by epitaxial growth temperature
In this work, we present a full set of InGaN LEDs based on a single optimal InGaN/GaN quantum design with emission wavelengths spanning from green to blue to violet by tuning the active layer growth temperature to precisely ...
High-quality InP/ZnS nanocrystals with high photometric performance and their application to white quantum dot light-emitting diodes
Full visible range covering InP/ZnS core-shell nanocrystals with high photometric performance have been prepared. Making use of these nanocrystals, we demonstrate a white quantum dot LED with a high color rendering index ...
Quantum efficiency enhancement in nanocrystals using nonradiative energy transfer with optimized donor-acceptor ratio for hybrid LEDs
(American Institute of Physics, 2009-06-17)
The quantum efficiency enhancement in nanocrystal solids is critically important for their efficient use as luminophors on color-conversion light emitting diodes (LEDs). For this purpose, we investigate energy gradient ...
