Nanocomposites based on multilayer carbon nanotubes (MCNT) and gallium selenide (GaSe) are synthesized by laser ablation. The structure and morphology of the nanocomposites are studied by X-ray phase method and atomic force microscopy (AFM). The atomic-force microscopy shows that the nanotube morphology changes insignificantly after laser ablation, but the nanotube size slightly increases and is 20-60 nm. The absorption and luminescence spectra of samples are studied experimentally under action of the second harmonic (h omega= 234 eV) of Nd:YAG laser. The MCNT/GaSe nanocomposites are shown to demonstrate an increased luminescence intensity (by a factor of similar to 5 as compared to individual components) and have a wide wavelength range (576-887 nm).
