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. 

We are starting the year with introducing the new product in the cathodoluminescence detection line: JOLT. This easy-to-use and budget-friendly detector is perfect for cathodoluminescence (CL) measurements of geological and optoelectronic samples.

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! 

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. 

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. 

Are you working with geological materials? Are you interested in learning about the most advanced techniques and tools to study your geological samples? Then join a two-day intensive workshop in Oslo, which will focus on advanced analytical tools and methods for geological applications. The workshop will consist of the lectures from invited speakers and hands-on sessions, which will cover cathodoluminescence (CL) tools & methods, EDS & EBSD tools & methods and mineralogy software.

A new paper on "Complementary cathodoluminescence lifetime imaging configurations in a scanning electron microscope" was published by researchers from AMOLF, McMaster University, McGill University, the Max Planck Institute for the Science of Light, University of Michigan, Delmic and Thermo Fisher Scientific. The paper introduces an elaborate analysis and comparison of time-resolved techniques and characteristics. 

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.

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.

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.
