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.

If you are working in the field of photovoltaics or optoelectronics, you know that perovskites, a group of materials that have ABX3 composition and a perovskite structure, have gained quite a lot of interest due to their exceptional performance in solar cell, light-emitting diode, laser, and water splitting devices.

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.

One of the applications of cathodoluminescence is studying optical nanoantennas. But what are they exactly? These devices, made usually from noble metals (gold or silver, for example) or from semiconductor materials, are capable of amplifying and manipulating light on the nanoscale.
Dr. Ruggero Verre is one the Delmic’s oldest customers: he is a post-doctoral researcher in the Department of Applied Physics at the Chalmers University of Technology in Gothenburg, Sweden. Optical nanoantennas is the focus of his research group, headed by Prof. Mikael Käll.
One way to study the properties of the antennas and understand how they work is by characterizing them with cathodoluminescence. The group of Ruggero Verre has been using the SPARC cathodoluminescence detector to study them, and they have achieved some interesting results.
