Synthesis of Zn_(1-x)Cd_xO bramble-like nanostructures

摘要

Ternary Zn_(1-x)Cd_xO bramble-like nanostructures with a Cd incorporation of about 6.7 at.% were produced onto Au-catalyzed Si substrate by thermal evaporation of Zn and Cd. The X-ray diffraction (XRD) analysis showed that the existence of lattice expansion in the c-axis orientation. The ultra-violet (UV) near-band-edge (NBE) emission of the Zr_(1-x)Cd_xO nanobrambles was red-shifted from 369 nm (3.37 eV) to 397 nm (3.13 eV) due to Cd substitution. The oxygen partial pressure was deemed as the critical experimental parameter for the formation of the bramble-like Zn_(1-x)Cd_xO nanostructures.
