Many colours from a single dot

19.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Physicists Bart van Dam and Katerina Newell (Dohnalova) from the UvA Institute of Physics, in collaboration with Emanuele Marino and Peter Schall as well as colleagues from the University of Twente and Jiljin University in China, have shown that a single nanoparticle can be used to emit different colours of light. Their results, which were published in the nano- and microphysics journal Small, show that the particles under consideration may be a very efficient and versatile tool to produce light of all colours at tiny scales.

Researchers invent light-emitting nanoantennas

19.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite. Such nanosources are based on subwavelength nanoparticles serving both as emitters and nanoantennas and allow enhancing light emission inherently without additional devices. Moreover, perovskite enables tuning of emission spectra throughout the visible range by varying the composition of the material. This makes the new nanoparticles a promising platform for creating compact optoelectronic devices such as optical chips, light-emitting diodes, or sensors. The results were published in Nano Letters.
