High efficiency deep blue OLEDs

High efficiency deep blue OLEDs

 · In this talk, we will firstly present a strategy to realize deep blue TADF OLEDs with the EQE of 28% and CIE y value of by narrowing the emission spectrum of blue TADF emitters along with high horizontal emitting dipole orientation. Secondly we will present deep blue OLEDs utilizing TTA process based on anthracene derivatives. For blueemitting anthracene derivatives, the theoretical ...

Bluetooth Low Energy

Bluetooth Low Energy

Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel appliions in the healthcare, fitness, beacons, security, and home entertainment industries. It is independent of classic Bluetooth [clarifiion needed] and has ...

Performance Efficiency

Performance Efficiency

This characteristic allows them to run substantially higher efficiency propellers – even in lower performance classes – than combustion engines. Propeller efficiencies in the lower horsepower class can vary by a factor of 3 between petrol outboards and Torqeedo electric outboards. To make the comparison easy for boaters used to shaft power ...

Lightemitting diode physics

Lightemitting diode physics

In lightemitting diode physics, the recombination of electrons and electron holes in a semiconductor produce light (or infrared radiation), a process called "electroluminescence".The wavelength of the light produced depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, design features of the devices such as special optical coatings ...

Mechanistic Study on High Efficiency Deep Blue AIE‐Based ...

 ·  · Aggregationinduced emission (AIE) materials are highly attractive because of their excellent properties of high efficiency emission in nondoped organic lightemitting diodes (OLEDs). Therefore, a deep understanding of the working mechanisms, further improving the electroluminescence (EL) efficiency of the resulting AIEbased OLEDs, is necessary.

Biological effects of highenergy visible light

Biological effects of highenergy visible light

Highenergy visible light (HEV light) is highfrequency, highenergy light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of biological effects, including those on the eye.. Despite a lack of any concurring scientific evidence, HEV light has sometimes been claimed to be a cause of agerelated macular degeneration.
