Energy-momentum cathodoluminescence technique applied to study plasmonic bullseye antennas

January 18, 2019

A new paper on "Energy-Momentum Cathodoluminescence Imaging of Anisotropic Directionality in Elliptical Aluminum Plasmonic Bullseye Antennas" was published in ACS Photonics by researchers Toon Coenen (Product Manager at Delmic) and Albert Polman (co-founder of Delmic and group leader at AMOLF). The paper for the first time introduces a completely new cathodoluminescence (CL) imaging technique called lens scanning energy-momentum (LSEK) cathodoluminescence.

Delmic's achievements in 2018 and plans for the next year

December 24, 2018

The holidays and the end of the year are just around the corner, so we would like to share with you the results of this year! 
Our SPARC CL detector was sold to several countries worldwide, including China, Germany, USA, Denmark and Australia. We are looking forward to exciting installations coming up next year. 

This year we added a new product to our SPARC product line: the LAB Cube. This time-resolved module allows to obtain lifetime and g(2) images. Another completely new product in the cathodoluminescence line will be announced at the beginning of the 2019, so stay tuned!

New possibilities for nanoscale light propagation with DNA-assembled plasmonic waveguides

December 11, 2018

A new interesting paper focusing on DNA-Assembled Plasmonic Waveguides for Nanoscale Light Propagation to a Fluorescent Nanodiamond was published in the prestigious journal Nano Letters by a team of researchers from King's College London, Stanford, and the technical university/Leibnitz institute in Dresden. The paper explores the possibilities of DNA-based nanofabrication applied to plasmonic waveguides and studied with cathodoluminescence imaging and electron energy loss spectroscopy.

How can zonation and crystallisation histories of sapphires be studied with cathodoluminescence?

December 07, 2018

We invite you to download the new white paper, which demonstrates the possibilities of studying alluvial sapphires from Australia with cathodoluminescence (CL) imaging. This research shows how cathodoluminescence can help to assess crystallisation histories of the precious gemstones and underlying causes for luminescence.

Time-resolved cathodoluminescence webinar is now available online

November 23, 2018

This morning, the first webinar on time-resolved cathodoluminescence took place. In this webinar our cathodoluminescence specialist Dr. Toon Coenen covered time-resolved techniques, such as lifetime imaging and g(2) imaging and the ways to perform them. He also dedicated part of his presentation to show the experiments that have been done with nanostructured semiconductor GaN. 

For those who have missed the opportunity to watch the webinar live, it is now available on our website for free.

Join the first time-resolved cathodoluminescence webinar!

November 01, 2018

Are you working with compound semiconductors for optoelectronics? Or are you studying single-photon emitters or phosphor materials? Then this webinar can show you new opportunities for your research.

Delmic is excited to invite you to our webinar on time-resolved cathodoluminescence, which will take place on 22nd of November, 9:30 AM (CET). This webinar will give you an overview of this imaging technique and how it can be applied in different fields. Time-resolved cathodoluminescence is a relatively new technique, which can be used to observe the time dynamics of cathodoluminescence emission process. It can be an extremely useful tool for getting insights into material properties as well as studying nanoscale quality and doing defect analysis.

Discovering secrets of the ocean: application note on marine microbiology

October 26, 2018

Deep down in the ocean, between and under the layers of the water, the secrets of the life itself are hidden, invisible to the naked eye. Studying marine microbes, which cover more than 70% of the earth and represent the world's largest ecosystem, can reveal information about ocean's chemistry and climate, and maybe even bring us closer to understanding how the life originated on our planet. 

Studying something as tiny as marine microbes can be extremely challenging. Microscopy proves to be a great tool for examining physiological and metabolic states of individual cells. Two types of imaging can be extremely effective. Fluorescence microscopy helps to image the function and provides information regarding metabolism of the organism. On the other hand, it is impossible to get information about ultrastructural composition of the sample. In order to identify cells and different communities of microbes a high resolution imaging, performed by electron microscopy, is required.
