Shelf‐Stable Quantum‐Dot Light‐Emitting Diodes with High Operational Performance [PDF]
Advanced Materials, 2020 AbstractQuantum‐dot light‐emitting diodes (QLEDs) promise a new generation of high‐performance, large‐area, and cost‐effective electroluminescent devices for both display and solid‐state lighting technologies. However, a positive ageing process is generally required to improve device performance for state‐of‐the‐art QLEDs. Here, it is revealed that the

Saturation compensation for visible light communication with off-the-shelf detectors
Optics Express, 2021 A photodetector may get saturated if the incident optical power approaches the detector saturation threshold. In such a case, a visible light communication (VLC) system fails to recover the useful transmitted signals. We introduce a saw waveform based response characterization technique when an off-the-shelf avalanche photo-diode (APD) is deployed ...

The Effectiveness of Light Shelf in Tropical Urban Context [PDF]
Environmental and Climate Technologies, 2016 AbstractLight shelf was developed to create uniform indoor illuminance. However, in hot climates the unshaded clerestory above the shelf transmits high solar heat gain. In dense urban context, these advantages and disadvantages might vary regarding the context and position of the fenestration.

A Study on Performance Evaluation of Mixed Light Shelf Type According to the Angle of Light Shelf
International Journal of Smart Home, 2015 A light-shelf, one of natural lighting methods, has advantages in constructability and economic feasibility in comparison with other passive natural lighting system. A movable light-shelf enables a user in a room to adjust the angle according to his or her preference to control the amount of indoor light. In addition, a light-self serves as a shield to
