A simple and low-cost method based on a heat-treating of Ni (NO3)2/SiO2film has been developed for fabricating NiO nanorings. The as-prepared nanorings have an inner diameter of 150-250nm and an average wall thickness (namely wire diameter) of approximately 20 nm on the surface of SiO2matrix. Furthermore, a growth mechanism, namely bubble-bursting bubbles as templates was tentatively proposed for understanding the formation of the NiO nanorings.
