Intergrowth Structure of Zeolite Crystals as Determined by Optical and Fluorescence Microscopy of the Template‐Removal Process

Growing together: The template-removal process in a series of zeolite crystals has been mapped by a combination of in situ optical and fluorescence microscopy. Three-dimensional spatial distribution of light-absorbing and -emitting species allowed visualization of the architecture of zeolite intergrowths.
