Watching nanowires grow! Self‐organization of CdTe nanocrystals into luminescent nanowires (see picture) takes place in a standard physiological phosphate‐buffered solution and is completed in several hours, as demonstrated in situ by means of confocal microscopy. Luminescence and Raman spectroscopy data evidence the occurrence of recrystallization processes during the nanowire formation.
