One-dimensional array of point-like light sources based on gold nanoparticles and tetracene: Preparation and possible operation mechanisms
- Institute of Physics, National Academy of Sciences of Ukraine, 46 Prospect Nauky, Kyiv-03680 (Ukraine)
A method of preparation of a linear close-packed array of point-like light sources based on a nanocomposite of gold nanoparticles and tetracene is proposed. Ordered system of microleads to the light sources with packing density up to 1000 mm{sup −1} consists of linear conducting chains of cobalt nanoparticles self-assembled in a magnetic field. The electroluminescence from the gold-tetracene nanocomposite occurs in the visible range typical of organic light-emitting field-effect transistors based on tetracene. A theoretical substantiation of the possibility of excitation of tetracene molecules by hot electrons emitted from the gold nanoparticles is suggested and compared with other possible physical mechanisms.
