ABSTRACT

The transmission spectra of GaSe thin films and nanoparticles obtained by laser ablation of a solid target in a liquid medium were experimentally studied. X-ray diffraction analysis showed that the crystalline structure of the nanoparticles is the same as that of the bulk material. It is shown that in GaSe nanoparticles the process of laser light absorption on structural defects is absent. It is shown that the observed luminescence is caused by radiative recombination of free excitons.

Keywords: thin films and GaSe nanoparticles, laser ablation, transmission spectra.
