Light extraction analysis and enhancement in a quantum dot light emitting diode [PDF]

, 2014
We apply a rigorous dipole model to analyze the light outcoupling and angular performance of quantum dot light emitting diode (QLED). To illustrate the design principles, we use a red QLED as an example and compare its performance with an organic light ...

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.

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 ...

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.
