This is because of the recombination of these generated charges at CGL with the charges inoculated by electrodes in the emissive layer
to produce photons.
The reason why the device could effectively regulate the shifting of the recombination zone is because the first emissive layer itself possesses an effective hole modulation barrier of 0.2 eV.
For example, in 2002, Forrest's group has reported that the CIE color coordinates of the OLED emission can be tuned over a wide range by inserting a 5 nm exciton blocking layer, BCP, between the emissive layers .
For the emissive layers
, which must be patterned, the company developed a nozzle printing process that simultaneously prints the red, green, and blue layers.
The matrix structure was illuminated by a terahertz beam from the metasurface side, while IR radiation from the emissive layer was detected by the IR camera.
The backside of the structure was covered with a high-performance infrared emissive layer. Absorption of terahertz radiation led to heating of the structure and increasing IR emission in the emissive layer, which was henceforth detected by the IR camera.
Black Panel" reproduces blacker blacks thanks to Pioneer's newly developed "Crystal Emissive Layer".
The "Crystal Emissive Layer" is a state-of-the-art technology that realizes the high performance and potential of plasma panels.
Recently we predicted the suitability of poly (9,97-di-n-octylfluorenyl-2.7-diyl) (PFO)/ Ti[O.sub.2] nanocomposite as an emissive layer
in OLED devices .
