Nanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that ...
A new film made of gold nanoparticles changes color in response to any type of movement. Its unprecedented qualities could allow robots to mimic chameleons and octopi—among other futuristic applications.
Chemists at RIKEN have discovered why shining light on silver nanoparticles causes oxygen molecules attached to their surfaces to break off. This insight will help researchers design new catalysts that harness light energy.
Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from ...
Terahertz lasers could soon have their moment. Emitting radiation that sits somewhere between microwaves and infrared light along the electromagnetic spectrum, terahertz lasers have been the focus of intense study due to ...
Researchers of Tomsk Polytechnic University with Russian and Danish teams have been able to experimentally confirm a plasmonic nanojet effect previously forecast in practice. Using a simple method, they focused surface plasmon ...
Highly energetic, "hot" electrons have the potential to help solar panels more efficiently harvest light energy.
Taking inspiration from nature's nanotech that creates the stunning color of butterfly wings, a University of Central Florida researcher is creating technology to make extremely low-power, ultra-high-definition displays and ...
A Toyohashi University of Technology research team has succeeded in developing a variable color sheet with a film thickness of 400 nanometers that changes color when stretched and shrunk. The developed stretchable color sheets ...
Nanophotonics uses light polarization as an information carrier in optical communications, sensing, and imaging. Likewise, the state of polarization of light plays a key role in the photonic transfer of quantum information. ...
