The Scherrer equation is a formula used in materials science and crystallography to estimate the size of crystalline domains in a material based on X-ray diffraction data. It provides a way to quantify the average size of coherently diffracting crystallites or grains within a sample. The equation is particularly useful for nanomaterials and thin films.
