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 (= 234 eV) of Nd: YAG laser. The MCNT/GaSe nanocomposites are shown to demonstrate an increased luminescence intensity (by a factor of ~5 as compared to individual components) and have a wide wavelength range (576–887 nm).
