Quantum-Dot-Induced Transparency in a Nanoscale Plasmonic Resonator

Electrodynamic simulations show that a single semiconductor nanocrystal can induce nearly complete transparency in the optical scattering and extinction of a metal nanostructure.

Handcrafting nanoparticles into superstructures with light

One of the Holy Grails of modern nanoscience is to assemble nanoparticles—tiny pieces of matter with diameters in the billionth of a yard range—into larger structures of any desired shape and form

Complexity in core-shell magnetic nanoparticles

Researchers at Purdue University and Argonne have found that the magnetic exchange bias coupling between core and shell depends critically on the "frozen spins" that reside at the interface between

Shedding new light on LEDs

LEDs, or light-emitting diodes, are the secret behind your iPhone screen, flatscreen TVs, Christmas lights and crosswalk signals. They can last longer and save more energy than traditional incandescent bulbs. But there is one thing they aren’t very good at: efficiently emitting light in the yellow-green spectrum.
