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.

Researchers Push Perovskite LEDs' Efficiency To Rivaling Best OLEDs

Researchers Push Perovskite LEDs' Efficiency To Rivaling Best OLEDs

Compared to OLEDs, which are widely used in high-end consumer electronics, the perovskite-based LEDs, developed by researchers at the University of Cambridge, can be made at much lower costs, and can be tuned to emit light across the visible and near-infrared spectra with high colour purity. Now, researchers have set a new efficiency record for LEDs based on perovskite semiconductors, rivalling that of the best Organic LEDs (OLEDs).

NEC Improves Workplace Efficiency with AR Solution Utilizing Smart Glasses

NEC Improves Workplace Efficiency with AR Solution Utilizing Smart Glasses

Tokyo, November 7, 2017 - NEC Corporation (NEC; TSE: 6701) today announced the development of an Augmented Reality (AR) solution to assist users with the selection of items through the use of smart glasses, a smart watch and new "ARmKeypad" functions. This solution enables users to perform tasks without having to look away from objects, making it ideal for use in manufacturing, logistics and other industries. Currently, NEC is carrying out demonstration tests at a hospital pharmacy and a manufacturing floor, where it has confirmed a reduction in workplace errors and working time thanks to the assistance of the new solution.

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze or shut down. Researchers at the University of Illinois at Urbana-Champaign and The University of Texas, Dallas have collaborated to optimize the crystal-growing process of boron arsenide – a material that has excellent thermal properties and can effectively dissipate the heat generated in electronic devices.

Fraunhofer IIS IoT-Bus: The Secure Communication Bus - Not Just for Lighting

Fraunhofer IIS IoT-Bus: The Secure Communication Bus - Not Just for Lighting

The Fraunhofer Institute for Integrated Circuits IIS is developing the IoT-Bus with IPv6 support and integrated security concept. It is a communication bus based on EIA/RS-485 and the IEEE 802.15.4 standard, which enables a secure and reliable data transmission of measured values and control commands and connectivity to the Internet of Things. The IoT-Bus forms a cross-media communication protocol and unites the two worlds of WPAN and fieldbuses without complex protocol conversion. The novel technology IoT-Bus is developed as part of the SEEDs project.

ZigBee Alliance and Thread Group Join Force

ZigBee Alliance and Thread Group Join Force

The ZigBee Alliance, an association of companies creating, maintaining and delivering open, global standards for the low-power wireless Internet of Things (IoT), and the Thread Group, an organization focused on making Thread the foundation for the Internet of Things in the home and beyond, today announced that multiple members of both organizations have demonstrated prototypes that run the ZigBee Alliance’s universal language for smart devices on Thread networks. The demonstrations, shown privately at the Thread Group’s Members Meeting in November and set for public display in both organizations’ booths at CES, are a key milestone in their liaison agreement, and highlight accelerating momentum behind an emerging ecosystem of connected products that will interoperate over Thread IP networks using the widely deployed ZigBee language.
