Ternary Zn1-xCdxO single-crystal bramble-like nanostructures with an incorporation Cd molar ratio of about 6.7% were synthesized by thermal evaporation of Zn and Cd on an Si substrate using Au as catalyst. The as-grown Zn1-xCdxO nanobrambles had a fairly uniform trunk with a diameter of approximately 100 nm. The diameter and length of the two-sided nano-thorns were about 10 and 100 nm, respectively. Ultra-violet (UV) near-band-edge (NBE) emission of the Zn1-xCdxO nanobrambles was red-shifted from3.37 to 3.14 eV due to the direct modulation of band gap caused by Cd substitution. The oxygen partial pressure was deemed as the critical experimental parameter for the formation of the bramble-like Zn1-xCdxO nanostructures.
