LED Research Finds A Way To Improve Operating Efficiency
March 21, 2023 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Osaka Metropolitan University scientists succeeded in directly observing how LECs change their electronic state. Light Emitting electrochemical Cells are attracting attention as one of the post-organic LEDs. LEC observation shows they change their electronic state over time during field emission. OMU scientists found the result by measuring their optical absorption via lamp light […]

Paul Scherrer Institute researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale, which means such diodes are practically made for use in large-area room lighting. Researchers have been searching for such materials for a long […]

A Silicon Quantum Dot White Blue LED Made
June 10, 2015 | Leave a Comment
Hiroshima University researchers have announced fabrication of a silicon quantum dot based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence. The hybrid LED is expected to be a next-generation illumination device for producing flexible lighting and displays. The fabrication was done by Professor Ken-ichi Saitow at the Natural Science Center for Basic Research and […]
