Semiconductor electronic devices can be made of either inorganic crystals, formed by the strong bonding of atoms and ions, or organic crystals, which demonstrate weaker bonds held together by van der Waals forces (weak electric ...
Lanthanide-doped nanoparticles (LnNPs) can harvest the near-infrared (NIR) light to emit higher energy photons (upconversion) or lower energy photons (downshifting). In a recent study published in ACS Nano, a team led by ...
A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...
Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency.
Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...
Liquid crystals are not solid, but some of their physical properties are directional—like in a crystal. This is because their molecules can arrange themselves into certain patterns. The best-known applications include flat ...
Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength light. Scientists from ...
Researchers from the University of Cambridge have used a suite of correlative, multimodal microscopy methods to visualize, for the first time, why perovskite materials are seemingly so tolerant of defects in their structure. ...
Nature knows several ways how to capture carbon dioxide (CO2). The most prominent one is photosynthesis, where sun light is used to fix CO2 into biomass. Nowadays, research groups around the world try hard to mimic this process ...
A collaborated team led by Prof. Su Fuhai from the Hefei Institutes of Â鶹ÒùÔºical Science (HFIPS) of the Chinese Academy of Sciences (CAS) recently identified the ultrafast dynamics in monolayer MoS2/ReSe2 heterostructures.
