چکیده
We report transparent quantum dot light-emitting diodes with a current focusing structure. By depositing SiO2 thin film to form the structure, DC density and luminance significantly increased over 8700 mA/cm2 360 000 cd/m2, respectively. The emission spectra densities as functions of thickness aperture width have been investigated discussed. This design is proved effective can be further applied other planar diode devices.

Vacuum-free transparent quantum dot light-emitting diodes with silver nanowire cathode
Efficient transparent quantum-dot light emitting diodes (QD-LEDs) are demonstrated by using a silver nanowire (AgNW) cathode. The devices are fabricated through a solution technique, not any vacuum processes are involved. Almost identical performance is obtained for both sides of the transparent device, which is primary due to the high transmittance of AgNW cathode. The maximum luminance (effic...
متن کاملExtremely Vivid, Highly Transparent, and Ultrathin Quantum Dot Light-Emitting Diodes.
Displaying information on transparent screens offers new opportunities in next-generation electronics, such as augmented reality devices, smart surgical glasses, and smart windows. Outstanding luminance and transparency are essential for such "see-through" displays to show vivid images over clear background view. Here transparent quantum dot light-emitting diodes (Tr-QLEDs) are reported with hi...

متن کاملDoped quantum dot@silica nanocomposites for white light-emitting diodes.
This work reports the use of a near-UV-LED chip in combination with blue, green-yellow and red emitting doped ZnSe QD@silica nanocomposites to construct a novel WLED with reduced scattering and no reabsorption. Blue, green-yellow and red emitting Cu or Mn doped ZnSe QDs with enlarged Stokes shifts and similar absorption peaks (360-410 nm) were synthesized in liquid paraffin in order to solve th...
متن کاملColor-tunable light emitting diodes based on quantum dot suspension.
We propose a color-tunable light emitting diode (LED) consisting of a blue LED as the light source and quantum dot (QD) suspension as the color-conversion medium. The LED color temperature can be controlled by varying the liquid volume of each QD suspension with different photoluminescence colors. We simulate and optimize the light efficiency and color quality of the color-tunable LED and also ...
