Latest achievements in nanophotonics, the SPARC and other topics discussed during CL workshop at AMOLF

June 05, 2018

On 31st of May Delmic together with AMOLF Institute in Amsterdam held the workshop “Cathodoluminescence for nanophotonics”, which gathered participants from the Netherlands, Germany, Switzerland, UK and Ireland. The workshop focused on cathodoluminescence imaging, the SPARC cathodoluminescence detector and various possibilities for the research in the fields of photonics and nanoplasmonics. In the evening the participants and the speakers enjoyed a dinner in the center of Amsterdam.

One step closer to efficient green LED devices

May 25, 2018

In the last few years, LEDs (light emitting diodes) have proved to be the future of the lighting systems, due to their efficiency, brightness, and longer lifetime. However, the systematic efficiency drop in the yellow-green region, also known as the “green gap”, is a fundamental limitation for the LEDs and semiconductor laser devices.

New paper by TU Delft sheds light on the optical properties of nanolasers

May 17, 2018

The researchers from the TU Delft, our close collaborator, have used cathodoluminescence lifetime measurements with the SECOM, to shed light on the optical properties of nanolasers. The results are presented in the new paper Nanoscale Imaging of Light-Matter Coupling Inside Metal-Coated Cavities with a Pulsed Electron Beam, which was published in Nano Letters last month. The study holds value for the field of nanophotonics as it demonstrates that the position of the material within the nanolaser influences its efficiency.

Automated detection of fluorescent cells for integrated light and electron microscopy: a new paper review

May 06, 2018

A new article was written by the researchers from the Francis Crick Institute, Delmic’s close collaborator. The paper, published in Journal of Microscopy, explains the new method of automated data acquisition for integrated light and electron microscopy. More specifically, the authors present a scheme for automated detection of fluorescent cells within thin resin sections for following electron microscopy imaging. This method aims to speed up the process of data acquisition and reduce the data rates.

Energy-momentum cathodoluminescence spectroscopy: new opportunities for nanophotonics

February 12, 2018

A new paper on Energy−Momentum Cathodoluminescence Spectroscopy of Dielectric Nanostructures was published in the renowned journal ACS Photonics. It focuses on mapping the local density of optical states (LDOS), which is fundamental to understanding nanophotonic systems and devices. Complete LDOS mapping, in energy, momentum, and real space, can be performed using cathodoluminescence spectroscopy.

New Application Note: Cathodoluminescence Imaging on Perovskites

February 06, 2018

We are excited to share with you the new application note on cathodoluminescence imaging on perovskites, prepared by our application specialist Toon Coenen. Perovskite is a collective term for materials that have a composition of the form ABX3 and a perovskite crystal structure. Recently it has received significant attention because of its potential to create cheap, flexible, and efficient optoelectronic devices such as solar cells and light-emitting diodes.
