Cathodoluminescence (CL) is a technique that can be used in conjunction with a scanning electron microscope (SEM) to study the optical properties of a sample. CL is a form of luminescence that occurs when a sample is irradiated with a beam of electrons. The electrons excite the atoms in the sample, causing them to emit light at specific wavelengths.
By adding a CL system to a SEM, researchers can obtain both structural and optical information about a sample. This can be useful in a variety of fields such as geology, materials science, and semiconductor technology.
In geology, CL can be used to study the mineralogy of rocks and minerals. It can be used to identify different minerals within a sample, and to study their optical properties such as color and fluorescence.
In materials science, CL can be used to study the properties of semiconductors, such as their band gap and defect density. It can also be used to study the properties of other materials, such as ceramics and glasses.
In semiconductor technology, CL can be used to study the properties of semiconductor devices, such as LEDs, solar cells, and transistors. It can be used to identify defects in the material and to study the distribution of dopants.
Overall, Cathodoluminescence (CL) in SEM can provide important information to researchers, allowing them to study the optical properties of a sample in addition to its structure and composition, allowing to gain a better understanding of the sample under analysis.
