Lanthanide-doped upconversion nanoparticles (UCNPs) demonstrate many superior properties of broadly-tunable multicolor emission and long emission lifetimes. This makes them well-suited for many light-emission applications. ...
A new nanoscience study led by a researcher at the Department of Energy's Oak Ridge National Laboratory takes a big-picture look at how scientists study materials at the smallest scales.
Metasurfaces are artificial materials adept at manipulating perception. With metasurfaces allowing lenses to be reduced to one 10,000th the size of conventional lenses, they are generating considerable interest as optical ...
Polarization describes the orientation of oscillations in a light wave, and it plays an essential role in various optical applications鈥攆rom enhancing visibility in sunglasses and camera lenses to facilitating advanced optical ...
Electro-optic modulators (EOMs) are cardinal elements in the optical communication networks that control the amplitude, phase and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance ...
When will the protruding rear camera on smartphones become obsolete? The implementation of a metasurface, which completely disregards the properties of light, promises to reduce the thickness of a camera lens to 1/10,000 ...
Quantum emission is pivotal to realizing photonic quantum technologies. Solid-state single photon emitters (SPEs), such as hexagonal boron nitride (hBN) defects, operate at room temperature. They are highly desirable due ...
A team of materials scientists and engineers at Stanford University, working with a colleague from ETH Z眉rich and another from Washington University in St. Louis, has developed a biochip that can be used to screen thousands ...
Using conventional testing techniques, it can be challenging鈥攕ometimes impossible鈥攖o detect harmful contaminants such as nano-plastics, air pollutants and microbes in living organisms and natural materials. These contaminants ...
A cutting-edge practice by two Vanderbilt researchers that enhances light in nanoscale structures could help in the detection of diseases like cancer.
