Open AccessEnvironmentally friendly quantum-dot color filters for ultra-high-definition liquid crystal displays
This work reports the synthesis and application of highly tuned cadmium-free green and red InPZnSe1−xSx/ZnS quantum dots (QDs) in QD enhanced liquid crystal displays (LCD). The emissions of the quantum dots were ...

Open AccessA new class of lightweight, stainless steels with ultra-high strength and large ductility
Steel is the global backbone material of industrialized societies, with more than 1.8 billion tons produced per year. However, steel-containing structures decay due to corrosion, destroying annually 3.4% (2.5 ...

Open AccessHigh-resolution patterning of colloidal quantum dots via non-destructive, light-driven ligand crosslinking
Establishing multi-colour patterning technology for colloidal quantum dots is critical for realising high-resolution displays based on the material. Here, we report a solution-based processing method to form p...

Open AccessInjection-modulated polarity conversion by charge carrier density control via a self-assembled monolayer for all-solution-processed organic field-effect transistors
We demonstrated modulation of charge carrier densities in all-solution-processed organic field-effect transistors (OFETs) by modifying the injection properties with self-assembled monolayers (SAMs). The all-so...

Open AccessDirect Optical Probing of Transverse Electric Mode in Graphene
Unique electrodynamic response of graphene implies a manifestation of an unusual propagating and localised transverse-electric (TE) mode near the spectral onset of interband transitions. However, excitation an...

Open AccessControlling the influence of Auger recombination on the performance of quantum-dot light-emitting diodes
Development of light-emitting diodes (LEDs) based on colloidal quantum dots is driven by attractive properties of these fluorophores such as spectrally narrow, tunable emission and facile processibility via so...
