# What you learn

- how complex-shaped perovskite structures can be studied with CL intensity maps
- how CL can (locally) determine the spectral emission characteristics
- why this imaging approach is not too destructive

## Cathodoluminescence Imaging of Three-Dimensional Methylammonium Lead-Halide Perovskite Structures

Read this application note to learn how cathodoluminescence (CL) imaging and spectroscopy provides a powerful method to study the optical properties of 3D perovskites structures on deep-subwavelength scales.
