ABSTRACT

InSe nanoparticles obtained by the interaction of laser radiation with the element In and a solution of SeO2 were experimentally studied. A pulsed Nd:YAG laser with a wavelength of λ=1064 nm, with a duration of 10 ns and an energy of 135 mJ per pulse was used as a radiation source. In the colloidal solution, the formation of nanoparticles with a diameter of 7 to 30 nm was observed. With the help of diffraction analysis of X-rays, a scanning electron microscope, an atomic force microscope, and spectroscopy of the dispersed energy of X-rays, the internal structure and structure of X-rays were studied samples. It is shown that the observed features in the luminescence spectra of InSe nanoparticles are due to the collective interaction of excitons. At high levels of
optical excitation, stimulated radiation was detected in InSe nanoparticles.

Keywords: InSe nanoparticles, laser ablation, absorption, stimulated radiation.
