All-inorganic perovskite quantum dot display breaks Cd-barrier

InterNano Industry News - December 5, 2015 - 4:45am
Ever since the first cadmium selenide quantum dot-based light-emitting devices (QLEDs) were reported in 1994, the dominant materials for QLEDs investigated since then have been limited to wurtzite or zinc blende Cd-based QDs. Similarly, the best developed and studied colloidal QD lasers have been fabricated from Cd-based semiconductors. Now, researchers have presented a new family of photoelectric materials for light-emitting devices: colloidal all-inorganic perovskite cesium lead halide QDs. This new material could find applications in LEDs and lasers, and has an especially big potential in high-performance displays, lighting, monochromatic narrow-band photodetectors, and optical communications.

Novel nanowire structures lead to white-light and AC-operated LEDs

InterNano Industry News - December 5, 2015 - 4:45am
Compared to the conventional inefficient incandescent and fluorescent lighting technologies, LED light bulbs can, in principle, operate at an efficiency level of 100%. The current LED lighting technology, however, is not even close to reaching this limit. This is due to several problems which, however, can be by and large solved by employing tunnel junction integration into current nanowire LED structures. Demonstrating this, researchers have developed tunnel junction nanowire LEDs that can eliminate the use of resistive p-GaN contact layers, leading to reduced voltage loss and enhanced hole injection.
