Zeolite crystals are embedded in nanofibers (see image) electrospun from dye‐doped polymer solutions containing the highly fluorescent zeolite L crystals. Dye‐loaded zeolites, integrated into nanowires with diameters in the range of 150 to 600 nm, are well oriented along the fiber axis, forming very bright nanometric light sources with visible polarized emission, which can be exploited in advanced nanodevices. This procedure provides a simple method to hierarchically organize an ensemble of emissive molecules.
