CuO/beta-Ga2O3 hybrid structures with enhanced and broadened light response from near-ultraviolet to visible light were successfully synthesized by a multi-cycle dipping and annealing process method. This novel synthetic pathway provides new possibilities for photodetection applications by integrating oxide heterojunctions.
CuO/beta-Ga2O3 hybrid structures with beta-Ga2O3 nanorods coated with CuO nanoparticle layers were successfully synthesized by a multi-cycle dipping and annealing process method. Compared with bare beta-Ga2O3 nanorods, the CuO/beta-Ga2O3 hybrid structures had greatly enhanced and dramatically broadened responses to light in the range from the near-ultraviolet to visible light. This novel synthetic pathway will provide new possibilities to prepare nanomaterials that integrate oxide heteroj unctions for photodetection applications.
