Silicon Quantum Dot Light Emitting Diode at 620 nm

Micromachines, 2019
Here we report a quantum dot light emitting diode (QLED), in which a layer of colloidal silicon quantum dots (SiQDs) works as the optically active component, exhibiting a strong electroluminescence (EL) spectrum peaking at 620 nm.

Method of Correcting Wind Tunnel Data for Omitted Parts of Airplane Models [PDF]

Wind tunnel models do not have complete similarity to the full scale airplane. Part of the dissimilarity is due to the difference between the stationary model in the artificial wind stream of the tunnel and the moving airplane in still air.

Progress in blue colloidal quantum dots for display applications

Journal of Information Display
Blue quantum dot light-emitting diodes (QLEDs) are key components in developing new generation display technology. To date, the performance of blue QLEDs, particularly the stability, is still far from the commercialization requirements.

Има ли ръжда в Стария завет? [PDF]

, 2006
Mony Almalech comments the fact that in the Old Testament the Hebrew word heled is never used in its primary meaning rust but in its different meanings (age, world, time). From the root of heled are derived the proper names Helday and Haluda.

Inverted Red Quantum Dot Light-Emitting Diodes with ZnO Nanoparticles Synthesized Using Zinc Acetate Dihydrate and Potassium Hydroxide in Open and Closed Systems

Micromachines
We developed inverted red quantum dot light-emitting diodes (QLEDs) with ZnO nanoparticles synthesized in open and closed systems. Wurtzite-structured ZnO nanoparticles were synthesized using potassium hydroxide and zinc acetate dihydrate at various ...

Insights into structural defect formation in individual InP/ZnSe/ZnS quantum dots under UV oxidation

Nature Communications
InP/ZnSe/ZnS quantum dots (QDs) stand as promising candidates for advancing QD-organic light-emitting diodes (QLED), but low emission efficiency due to their susceptibility to oxidation impedes applications. Structural defects play important roles in the
