Electroluminescence efficiency enhancement in quantum dot light-emitting diodes by embedding a silver nanoisland layer
A colloidal quantum dot light-emitting diode (QLED) is reported with substantially enhanced electroluminescence by embedding a thin layer of Ag nanoislands into hole transport layer. The maximum external quantum efficiency ...
Continuously tunable emission in inverted Type-I CdS/CdSe core/crown semiconductor nanoplatelets
The synthesis and unique tunable optical properties of core/crown nanoplatelets having an inverted Type-I heterostructure are presented. Here, colloidal 2D CdS/CdSe heteronanoplatelets are grown with thickness of four ...
Stable and low-threshold optical gain in CdSe/CdS quantum dots : an all-colloidal frequency up-converted laser
An all-solution processed and all-colloidal laser is demonstrated using tailored CdSe/CdS core/shell quantum dots, which exhibit highly stable and low-threshold optical gain owing to substantially suppressed non-radiative ...
Liquid-liquid diffusion-assisted crystallization : a fast and versatile approach toward high quality mixed quantum dot-salt crystals
Here, a new, fast, and versatile method for the incorporation of colloidal quantum dots (QDs) into ionic matrices enabled by liquid–liquid diffusion is demonstrated. QDs bear a huge potential for numerous applications ...
Nonradiative energy transfer in a layered metal-dielectric nanostructure mediated by surface plasmons
Nonradiative energy transfer (NRET) has been applied in various applications of Nanosensors, Raman scattering, color tuning, light harvesting and organic light emitting structures. Due to the small range of donor-acceptor ...
