In our previous application note 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 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, show (efficient) light emission throughout these perovskites structures.
