In our [previous application note](https://request.delmic.com/application-note-cathodoluminescence-imaging-on-perovskites-2) we already described exceptional performance of perovskite materials in solar cells, light-emitting diodes and lasers.  While most of the time perovskites are grown in a more traditional shape of thin-films and nanocrystals, it was discovered recently that with the use of carbonate salts perovskite materials can take a large variety of complex 3D shapes.  [Cathodoluminescence (CL) imaging](https://www.delmic.com/cathodoluminescence) is a powerful method to study the optical properties of such structures on a deep-subwavelength scales. The intensity maps, acquired with the [SPARC cathodoluminescence detector](https://www.delmic.com/sparc-cathodoluminescence-sem), show (efficient) light emission throughout these perovskites structures.
