News LEDs

• Copper, gold and tin for efficient chips

  They are particularly small, durable and economical: LEDs have conquered the automotive industry; it is already possible today to recognize the make of a car by the design of the LED headlights. Whether in the interior, displays, infotainment system or brake lights, parking lights or fog lights – a more

• A Bright Future for Silicon

  US scientists at the University of Texas at Austin and Cornell University have fabricated the first ordered arrays of silicon nanocrystals reported to date. Brian A. Korgel and colleagues developed a new chemical method to generate tiny silicon crystals—or quantum dots—with precisely controlled size more

• Carl Zeiss Grants Sublicense for LED Fluorescence Excitation to Prior Scientific Ltd.

  Effective retroactively to 1 June 2011, the Microscopy business group of Carl Zeiss has granted a sublicense for patents relating to LED fluorescence excitation in microscopy to Prior Scientific Ltd., Cambridge, UK. These patents protect the use of light emitting diodes for the excitation of fluores more

• Sensors, Vol. 13, Pages 5614-5629: Inertial Sensor-Based Two Feet Motion Tracking for Gait Analysis

  Two feet motion is estimated for gait analysis. An inertial sensor is attached on each shoe and an inertial navigation algorithm is used to estimate the movement of both feet. To correct inter-shoe position error, a camera is installed on the right shoe and infrared LEDs are installed on the left sh more

• Freestanding Luminescent Films of Nitrogen-Rich Carbon Nanodots toward Large-Scale Phosphor-Based White-Light-Emitting Devices

  In this work, nitrogen-rich carbon nanodots (CNDs) are prepared by the emulsion-templated carbonization of polyacrylamide. The formation mechanism and chemical structure are investigated by infrared, nuclear magnetic resonance, and X-ray photoelectron spectroscopies. Transmission electron microscopy more

• Effect of Particle Size on the Optical Properties of Yellow Silicate Phosphor in Light‐Emitting Diodes

  Understanding the effect of particle size on the optical properties of phosphor is important to increase packaging efficiency in white light‐emitting diodes (LEDs). We have investigated the effect of particle size (10–20 μm, 20–25 μm, 25–32 μm) on the optical properties of a yellow silicate phosph more
