Cathodoluminescence imaging on quartz in sandstone

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.

New possibilities for studying (compound) semiconductors with cathodoluminescence and time-resolved imaging techniques

Posted by Delmic on Nov 9, 2018 9:55:14 AM

In the last few decades, electronic devices have become more and more important in our lives, and semiconductors are a crucial part of this technology innovation. A semiconductor is a generic term for materials, normally solid chemical elements, that can conduct current, but only partly. A semiconductor has a conductivity which is between that of an insulator with almost no conductivity, and a conductor with almost full conductivity.

Studying optical nanoantennas: customer story from Chalmers University of Technology

Posted by Delmic on Jun 18, 2018 12:15:00 PM

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.
