Such a single-value can serve as supplementary parameter that quantifies a measure of downward luminous emissions.
The PHOLEDs with BTCz exhibited efficient blue emission with luminous and quantum efficiencies of 30.9 cd/A and 15.5% at 1000 cd/m2, respectively.
Devices tested in air are shown to exhibit emission spectra, luminous efficiencies, and lifetimes similar to literature values for devices fabricated in nitrogen environments.
The direct images and chemiluminescence spectra show that the spray flames have three regions: the blue flame region, which has a peak of CH* and C2* radical chemiluminescence, luminous flame region caused by soot emission, and blue emission region caused by CO2 emission.
Luminous intensity of LED emissions was set at 1 Cd using this formula.
These are the more luminous objects that usually show emission lines, and which should not be missed in the survey unless they are heavily reddened.
Among those, the device using 1 exhibited the efficient blue emission with a luminous efficiency of 4.56 cd/A, power efficiency of 1.95 lm/W, an external quantum efficiency of 3.42%, and CIE x,y coordinates of (0.15, 0.17) at 20 mA/cm2, respectively.
An indirect-emission type of luminous organ is present in some fish.
For OLEDs to be useful in displays application, true red, green, and blue emissions of sufficient luminous efficiencies and proper chromaticity are required.
Before the SI onset marked by the downward black arrow, the auroral images display the discrete type aurora in dayside corona elongated in the east-west direction at near the northernmost portion of the FOV, which is the luminous band and stable structured auroral emission intersecting with minor beams of auroral electrons at the edge of the FOV.
