Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared

Colloidal Quantum Dots Make LEDs Shine Bright in the Infrared ICFO researchers report on the development of a colloidal quantum-dot light emitting diode with unprecedented quantum and power conversion efficiencies in the infrared range. The ideal optoelectronic semiconductor material should be a strong light emitter i.e. should emit light very efficiently upon optical excitation as well as be an efficient charge conductor to allow for electrical injection in devices. These two conditions when met can lead to highly efficient light emitting diodes as well as to solar cells with the possibility to approach the Shockley-Queisser limit. Until now the materials that have come close to meeting these conditions have been based on epitaxially-grown costly III-V semiconductors that cannot be monolithically integrated to CMOS electronics.

“UV Power” Research Project Is Working on LED-Replacements for Conventional UV Light Sources

“UV Power” Research Project Is Working on LED-Replacements for Conventional UV Light Sources Since February 2017, a total of five research institutes and companies have been working on “UV Power”, a collaborative project funded by the German Federal Ministry of Education and Research (BMBF). The partners have made it their goal to provide high-power UV LEDs to cover a wide variety of applications. These LEDs will eventually replace conventional UV light sources, which often contain toxic mercury, in areas such as production, disinfection, the environment, life sciences and medicine. UV LEDs are also likely to open up new areas of application. Read more »
