NIST Develops GaN Core-Shell Nanowire UV LED with 5 Times Intensity

A research team at National Institute of Standards and Technology (NIST) has developed nanowire UV LEDs that are able to produce five times higher light intensity based on a simpler shell design. UV LEDs are used in a growing number of applications such as polymer curing, water purification and medical disinfection. Researchers at NIST have been trying to make nanowire-based LEDs for scanning-probe tips intended for electronics and biology applications. Lately, researchers have been experimenting with nanowire cores made of silicon-doped GaN, which has extra ...

New Measurement of LED Brightness and Color

The researchers from the National Institute of Standards and Technology (NIST) have developed a new, economical method for measuring the optical properties of high power LEDs to allow LED lighting manufacturers to obtain accurate, reproducible, and comparable measurements of LED brightness and color. By mounting the LED on a temperature controlled heat sink, the researchers can test the LEDs at their normal operating temperature at high speed.
