In the present work, we report the growth of all-inorganic perovskite nanorings with dual compositional phases of CsPbBr3 and CsPb2Br5 via a facile hot injection process. The self-coiling of CsPbBr3-CsPb2Br5 nanorings is driven by the axial stress generated on the outside surface of the as-synthesized nanobelts, which results from the lattice mismatch during the transformation of CsPbBr3 to CsPb2Br5. The tailored growth of nanorings could be achieved by adjusting the key experimental parameters such as reaction temperature, reaction time and stirring speed during the cooling process. The photoluminescence intensity and quantum yield of nanorings are higher than those of CsPbBr3 nanobelts, accompanied by a narrower full width at half maximum (FWHM), suggesting their high potential for constructing self-assembled optoelectronic nanodevices.
