Phosphors Optimized for Better, Brighter LEDs
New guidelines for optimizing phosphors — a key component in white LEDs — could lead to brighter and more efficiently produced solid-state lighting. “So far, there has been no complete understanding of what make some phosphors efficient and others not,” said Ram Seshadri, a University of California, Santa Barbara professor. “These guidelines should permit the discovery of new and improved phosphors in a rational rather than trial-and-error manner.”

IR Remote Sensor Combines Detection, Imaging
A new dual-band remote sensor splits the infrared radiation given off by an object into a long-wave portion for detection and into a mid-wave portion for spectral analysis to simultaneously detect and image an IR source.

The Perfect Solution for Photoluminescence Studies of Lanthanide-Doped Semiconducting Nanocrystals
Optical Building Blocks Corp.
Photoluminescence (PL) studies of lanthanide-doped semiconducting nanocrystals have become very common in materials science. The increased research interest in such materials is prompted by applications in solar energy conversion devices, lasing media, LED technologies and development of upconversion-based luminescent labels for biomedical analyses and bioimaging. The new Quattro™ bench-top luminescence spectrometer is the ideal tool to fully characterize the PL properties of such materials in the UV-VIS range.

The Past, Present and Future of Freeform Optics
Wednesday, November 13, 2013 - 1:00 PM EST
FREE WEBINAR
Jannick P. Rolland

Speaker: Jannick P. Rolland
The Institute of Optics, University of Rochester
The emerging, transformative area of freeform optics could allow for a wider range of lens and mirror shapes than strictly spherical, and for more targeted applications. In this one-hour webinar, Professor Jannick Rolland will provide a short historical context to this emergence and discuss the challenges as well as the rapidly emerging knowledge that spans from the mathematics of freeform surfaces to the implementation of freeform optical systems.
