Abstract

Abstract: InSe nanoparticles obtained by laser ablation in a liquid are experimentally studied. A pulsed laser (Nd : YAG) with λ = 1064 nm, a duration of 10 ns, and an energy density of 135 mJ/cm2 is used as an emitter. Using X-ray diffraction analysis, the structure and size of the nanoparticles are determined to be 10–45 nm. The observed features of the absorption and photoluminescence spectra of indium selenide nanoparticles are due to the interband transition and discrete energy levels located above the conduction band. Nonlinear optical phenomena caused by changes in the refractive index of the medium are observed in the InSe nanoparticles.
