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.

Studying formation of sedimentary rocks and crystallization histories of sapphires with the same technique: cathodoluminescence

Posted by Delmic on Dec 18, 2018 1:00:00 PM

Studying formation of sedimentary rocks, observing changes in the chemical composition of zircons, and understanding underlying causes for luminescence of sapphires: all of these are possible with one versatile technique. Cathodoluminescence (CL) is a very useful method of data acquisition in geosciences as it reveals information not readily provided by other techniques.

The excitation of electrons in the sample that produces the light seen through a cathodoluminescence system occurs in specific chemical impurities or intrinsic defects within a geological structure.

Integrated correlative light and electron microscopy: A new technique for geological materials

Posted by Delmic on May 3, 2018 3:00:00 PM

Integrated correlative light and electron microscopy (iCLEM) is a technique, in which both fluorescence imaging and electron imaging can be performed on one instrument without needing to transfer the sample. Correlative microscopy approach is being used worldwide for cancer research, in marine biology, neuroscience, and cell biology. Recently this technique has also been applied in the field of geology to gain an insight into the sedimentary organic matter in geological materials.
