When an electron beam interacts with a material, a multitude of processes
The radiation that is generated in the ultraviolet/visible/near-infrared regime of the electromagnetic spectrum is referred to as cathodoluminescence (CL) as the radiation is generated by cathode rays (fast electrons). The electron beam causes the material to fluoresce as it returns to a ground state.
Figure 1: Schematic of the processes that occur when an energetic beam of electrons impinges on a sample. These processes are used for different characterization techniques as indicated in the schematic. Cathodoluminescence is the electromagnetic radiation in the UV/VIS/IR spectral range.
SPARC cathodoluminescence detection system
The SPARC is a cathodoluminescence detector that is designed and produced by Delmic. This system can be retrofitted to any scanning electron system (SEM) to produce high-performance cathodoluminescence images.
This cathodoluminescence detection is unique for its ease-of-use and optimal collection and detection of cathodoluminescence emission.The sensitivity and ease of use make it possible to take any cathodoluminescence application to the next level.
