Indoor daylight illuminance: a comparison between experimentally determined varying CIE sky-type and a predefined CIE sky model

open access: yes, 2019
The output accuracy of the building performance simulation tools depends on the employed models. Most daylighting simulation tools evaluate the daylight performance in built-environment through illuminance based metrics, and refer the Perez all weather ...

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

open access: yesFlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.

Assessment of gingivitis with photocolorimetry: The CIE L*, a*, and b* color parameters of human gingiva.

open access: yes, 2003
The need to objectively measure the color of human gingiva has been the subject of many studies. However, no one has yet succeeded in measuring the true color of human gingiva.

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Carbonyl lock enables multi‐resonant organoboron framework with substantially enhanced spin‐flip and reduced emission bandwidth

open access: yesFlexMat, EarlyView.
Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Highly efficient blue crystalline organic light‐emitting diodes enabled by a hot exciton sensitizer PyPO

open access: yesFlexMat, EarlyView.
Two different sensitization structures (hot exciton sensitizer type and exciton nanoaggregate type) were integrated into crystalline host matrix. The resulting crystalline organic light‐emitting diodes exhibit low Joule heat loss ratio and high photon output.
