At the Paul Scherrer Institute (PSI), researchers have discovered a green luminescent substance that could enable OLEDs to deliver high light yields inexpensively and on a large scale. Many of the materials that have been considered for OLEDs contain expensive additives such as iridium, making their large-scale application impractical. The researchers at PSI turned to the copper-containing compound CuPCP. Copper is a relatively inexpensive metal, and the compound CuPCP can be easily produced in large quantities. CuPCP gives off an intense green glow not only when current is...Read full articleRelated content from Photonics MediaARTICLESNew Red Phosphor Could Make LEDs More Energy-EfficientA team at the University of Innsbruck, in cooperation with OSRAM Opto Semiconductors, has synthesized a new high-performing red phosphor for LEDs that could make LED lighting more energy-efficient....Photonics Spectra July 2019 IssueSelf-Heating in OLEDs Can Cause Decrease in LuminanceWhen LEDs and transistors are connected in parallel, even slight differences in resistance can lead to imbalanced current flow.

Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...Photonics HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market.
