An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...
Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...
In modern devices, such as phone screens or advanced sensors, light is often generated by pairs of organic molecules, where one molecule, known as the donor, transmits electrons, and the other, ...
To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...
Light emitting diode demonstration box, 1996. Paper label on front: "InGaN SQW LED / UCSB MOCVD Lab" [Indium Gallium Nitride [SQW] Light Emitting Diode / University of California Santa Barbara Metal ...
LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle ...
At-home LED devices, particularly those that combine red and blue light, are efficacious for acne and can likely complement other over-the-counter and prescription treatments. HealthDay News — At-home ...
Just a general observation: when your project’s BOM includes ytterbium metal, chances are pretty good that it’s something interesting. We’d say that making your own OLED displays at home definitely ...
Light-emitting diode (LED) light therapy is a cosmetic and medical treatment that uses LED wavelengths to treat various skin conditions, such as acne and psoriasis. You can get this therapy at a ...
