A study published in Nano Letters demonstrates the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space. Pohang University of Science and Technology (POSTECH) ...

A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green. "These materials ...

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

Work on tiny dots that light up TV screens and help doctors see the blood vessels that feed tumors has earned three scientists the 2023 Nobel Prize in chemistry. Chemist Moungi Bawendi, chemist Louis ...

(Nanowerk Spotlight) Augmented-reality glasses and near-eye microdisplays need tightly packed light-emitting pixels. At that scale, a pattern can fail even when it looks correctly drawn. A narrow ...
