Measuring time dynamics with time-resolved cathodoluminescence

Posted by Delmic on Jul 17, 2019 10:37:00 AM

Cathodoluminescence has established itself as a powerful technique for measuring and understanding various properties of light. In the previous blog posts, we explained how intensity mapping can be used to measure amplitude of the electromagnetic waves, hyperspectral CL for wavelength measurements, angle-resolved CL for wave vector, and polarimetry for polarization. These properties of light are not static, which means that there is time dynamics associated with light, which can also be studied. How? Keep reading!

CL intensity mapping: ideal imaging technique for geological samples

Posted by Delmic on May 30, 2019 11:49:00 AM

One of the fastest and most straightforward techniques for understanding the composition and structure of geological samples is intensity mapping. What is it exactly? This imaging mode allows quickly obtaining cathodoluminescence contrast of the sample by acquiring CL intensity for every beam position.

The most modular cathodoluminescence detector: The SPARC

Posted by Delmic on May 15, 2019 1:30:00 PM



When adding the new equipment to the lab, it is important to consider a lot of various factors. One of such factors is how much experimental freedom the new system can offer. Not only it has to be configured specifically to cater your scientific needs, but also, ideally, it has to be modular in order to change as your experiments evolve.

What is Hyperspectral Cathodoluminescence?

Posted by Delmic on Apr 24, 2019 1:09:00 PM

For the past few weeks we have been focusing on possibilities of cathodoluminescence imaging of the SPARC CL detector. In this post we describe hyperspectral cathodoluminescence, which is a powerful tool for wavelength spectrum visualisation.

Spectrally and angular-resolved cathodoluminescence explained

Posted by Delmic on Mar 27, 2019 2:20:00 PM

What is spectrally and angular-resolved(also known as energy-momentum) CL?

In the last blog post we explained angle-resolved cathodoluminescence imaging, a technique which is used to acquire angular profiles and gain a better understanding of materials' optical properties. The imaging technique that we are focusing on this week combines information acquired with angle-resolved imaging and high-resolution spectroscopy. This technique is called Lens-scanning energy-momentum(LSEK) Imaging, or full Angle-Resolved Spectroscopy, and it allows collecting a full emission spectrum for each emission angle. This new imaging technique is now available with the SPARC system. Keep reading if you would like to understand how it works and what results can be achieved.

6 imaging modes of cathodoluminescence detector

Posted by Delmic on Feb 27, 2019 2:18:00 PM

Cathodoluminescence is a great tool for obtaining valuable information about the properties of a sample. This data can help researchers and developers get a better understanding of possible defects, efficiency of the material and other properties. 

The SPARC cathodoluminescence detector has 6 imaging modes which can enhance your research and provide you with an important information about your samples. Keep reading if you would like to know what exactly is possible with these modes!

How to study properties of rare-earth doped materials with cathodoluminescence

Posted by Delmic on Feb 20, 2019 3:09:00 PM

Rare-earth elements, also known as REE, are a group of elements, consisting of scandium, yttrium and 15 lanthanide elements. In the last decades there has been a significant growth in the number of devices that use rare-earth metals. They can be found in a wide range of technological areas and are commonly used in lighting and displays, CT scanners and electron microscopes, (fiber) lasers and amplifiers, anti-cancer agents, fluorescent markers, batteries, magnets and catalysists. Rare-earth elements are crucial for modern-day technology and it is important to study rare-earth doped materials at nanoscale to understand them better.
