New Application Note: Cathodoluminescence Imaging on Perovskites

We are excited to share with you the new application note on cathodoluminescence imaging on perovskites, prepared by our application specialist Toon Coenen. 

Perovskite is a collective term for materials that have a composition of the form ABX3 and a perovskite crystal structure. Recently it has received significant attention because of its potential to create cheap, flexible, and efficient optoelectronic devices such as solar cells and light-emitting diodes.

A fully inorganic perovskite material (CsPbIBr2) is the main focus of the note. Cathodoluminescence (CL) microscopy was used to investigate material changes occurring on microscopic length scales. During CL imaging the beam was raster scanned over the surface of the sample spectroscopic and intensity data was collected. The knowledge gained from the results can potentially be used to improve device performance.

We invite you to download the application note below. If you are interested in cathodoluminescence imaging applied in various scientific fields (nanophotonics, geology, materials science) explore our resource library.
