Growth of Submicrometer-Scale Rectangular Parallelepiped Rutile TiO₂ Films in Aqueous TiCl₃ Solutions under Hydrothermal Conditions

Evolution of a new morphology of rutile TiO2 films consisting of nearly single-crystalline parallelepipeds was achieved through hydrothermal treatments of aqueous TiCl3 solutions in the presence of NaCl
