At night, prolonged exposure to light could have negative impacts on human health. However, Japanese scientists have currently found a new kind of light with very few consequences for physiological variations during sleep.
Anglia Components is expanding its range of Ultraviolet LED solutions through a new partnership with Bolb, a leading developer of some of the most efficient and high performance UVC LEDs in the industry.
The University of Michigan has created a novel electrode that could allow organic light-emitting diodes to produce 20% more light. It might help lengthen the battery life of smartphones and laptops, as well as improve the energy efficiency of next-generation televisions and displays.
Organic light-emitting diodes are widely used in display technology and are also being investigated for lighting applications.
An international research team has devised a new method that could be used for making low-cost, more efficient light-emitting materials that are flexible and can be printed using ink-jet methods.
To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs.
A lucky break has shown silicon is a powerful material for use in the manipulation of light.
Scientists have discovered a new technique to measure the distribution of compositional changes in the indium gallium nitride (InGaN) quantum wells (QWs) at varying amounts of indium.
The inclusion of a special new perovskite layer has enabled scientists to create a "spin-polarized LED" without needing a magnetic field or extremely low temperatures, potentially clearing the path to a raft of novel technologies.
Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.
