Multilayered nanocrystalline SnO 2 hollow microspheres (MHS‐SnO 2 ) of a rutile structure with a controllable morphology have been successfully synthesised via a chemically induced self‐assembly method by using tin chloride pentahydrate and sucrose as precursors in the glycol–water aided solvothermal synthesis. The morphology, composition, structure and luminescent properties of MHS‐SnO 2 are characterised by field‐emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high‐resolution transmission electron microscopy (HRTEM) with selected area electron diffraction, X‐ray diffraction, Raman spectroscopy and photoluminescence spectroscopy. The FESEM, TEM and HRTEM images indicate that the as‐prepared microspheres show a multilayer structure and the walls of the hollow microspheres are composed of single crystalline nanoparticles. The effect of calcinating temperature on the Raman and optical properties of the product is analysed and a self‐assembly growth mechanism of the MHS‐SnO 2 is proposed.
