    • Metal-polymer hybrid nanomaterials are provided. The hybrid nanomaterials comprise nanotubes or nanowires and metal layers formed on the inner or outer surfaces of the nanotubes or the outer surfaces of the nanowires. The nanotubes or nanowires include a light-emitting π-conjugated polymer and the metal layers are composed of a metal whose surface plasmon energy level is close to the energy band gap of the nanotubes or nanowires. Further provided are a method for preparing the hybrid nanomaterials, a method for controlling the optical properties of the hybrid nanomaterials, and an optoelectronic device using the hybrid nanomaterials. Energy transfer and electron transfer based on surface plasmon resonance increases the number of excitons in the conduction band of the nanotubes or nanowires including the light- emitting polymer, resulting in a remarkable increase in the luminescence intensity of the metal-polymer hybrid nanomaterials. The metal-polymer hybrid nanomaterials are easy to prepare and inexpensive while possessing inherent electrical and optical properties of carbon nanotubes. In addition, the electrical and optical properties of the metal-polymer hybrid nanomaterials can be easily controlled. Based on these advantages, the metal-polymer hybrid nanomaterials can be applied to a variety of optoelectronic devices, including light-emitting diodes, solar cells and photosensors.
