New material concept allows more cost-effective production of blue organic light-emitting diodes

14-Sep-2023 - Blue organic light-emitting diodes (OLEDs), which can be used in smartphones, televisions or other devices, are still difficult to manufacture today. A team of researchers led by Gert-Jan Wetzelaer of the Max Planck Institute for Polymer Research has now developed a new material concept that ...

Molecular highway for electrons in organic light-emitting diodes

New material concept potentially allows efficient blue OLEDs with strongly simplified structure

27-Jul-2023 - Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colours red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which could be partly circumvented by using highly ...

Luminous Molecules

Chemists smooth the path for new and better light sources

13-Apr-2023 - Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the path for new and better light sources. They ...

Nanoantennas directing a bright future: White LEDs may soon be dethroned

Titanium oxides found to significantly increase efficiency and photoluminescence

23-Dec-2022 - White LEDs may soon be dethroned as the world's go-to light source by an alternative with a much better sense of direction. As a next-generation optical control technology, aphotonic crystalornanoantennais a two-dimensional structure in which nano-sized particles are arranged periodically on ...

UV micro-LEDs for sensing, production and communication

The tiny LEDs can be densely packed to form high-resolution arrays

12-Jul-2022 - Researchers at the Ferdinand-Braun-Institut (FBH) in Berlin have successfully produced the first prototypes ofmicro light-emitting diodes that emit in the ultraviolet spectral range (UVB). The micro-LEDs with 310 nanometers (nm) emission wavelength feature a small size of the emitting area with ...

World’s first LED lights developed from rice husks

19-Apr-2022 - Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their ...

Sustainable Chemistry Based on Wood

Producing materials for solar cells, light-emitting diodes and other organic electronics applications as sustainably as possible

17-Feb-2022 - Some hikers carry a small solar power plant with them: a foil is attached to their backpack that converts sunlight into electricity. This allows them to charge their mobile phone while on the move. Flexible, thin and lightweight solar panels can also be attached to outdoor clothing or glued to ...

How water surfaces can be used to produce functional materials

19-Oct-2021 - The production of high-quality monolayers – i.e. only one molecule high - is highly relevant for optoelectronic components such as organic light-emitting diodes used today in modern cell phones: Both lifetime and energy efficiency can be increased. Scientists at the Max Planck Institute for ...

How cola still tingles after a year

A few nanometers of thin quartz-like coatings can multiply the shelf life of food, enable brilliant OLED TV pictures or separate gases from each other

10-Aug-2021 - If polymers are specifically made to form and deposit on the surfaces surrounding the plasma, they can be coated in a targeted manner. Thanks to this so-called Plasma Enhanced Chemical Vapor Deposition, or PECVD for short, it is possible, for example, to apply ultra-thin, gas-tight coatings to ...
