Lifetime cathodoluminescence mapping: new imaging mode of the SPARC will be presented during IMC19

August 15, 2018

During the IMC19 in Sydney Delmic will present new imaging modes of the SPARC system: time-resolved cathodoluminescence imaging(g(2) and lifetime mapping). Measurements acquired with these imaging modes can be extremely valuable for a large range of applications. The new technical note explains the mechanism of the lifetime mapping and its possibilities for various applications.

3D shapes of perovskite: new application note on cathodoluminescence imaging

July 04, 2018

The new application note, prepared by our application specialist Toon Coenen, focuses on the methylammonium lead halide perovskite materials. In our previous application note we already described exceptional performance of perovskite materials in solar cells, light-emitting diodes and lasers. 
While most of the time perovskites are grown in a more traditional shape of thin-films and nanocrystals, it was discovered recently that with the use of carbonate salts perovskite materials can take a large variety of complex 3D shapes.

How can correlative microscopy reveal unique insights into your sample (in one infographic)

June 11, 2018

Imaging biological samples can be pretty tiring and difficult, especially when the data has to be acquired with different microscopes. Transferring the sample, acquiring data and overlaying the images can be extremely laborious. Correlative light and electron microscopy (also known as CLEM) is an imaging technique that eliminates these challenges by combining light microscope with a scanning electron microscope, making the process of image acquisition and overlaying seamless and user-friendly.

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.
