Abstract

The absorption and luminescence spectra of InSe and GaSe nanoparticles and InSe/GaSe and GaSe/InSe nanoheterostructures based on them synthesized by laser ablation in a liquid are studied experimentally. A pulsed Nd:YAG-laser with built-in generators of the second and third harmonics intended for generation of radiation with wavelengths 1064, 532, and 335 nm is used as the radiation source. The ablation is carried out in a quartz cell with distilled water using the Nd:YAG laser with wavelength lambda = 1064 nm, pulse duration 10 ns, pulse energy 135 mJ, and pulse repetition frequency 10 Hz for similar to 10 min. The energy-gap widths of the InSe and GaSe nanoparticles are calculated by the Tauc method. InSe/GaSe and GaSe/InSe semiconductor/semiconductor nanoheterostructures are shown to form on the base of InSe and GaSe nanoparticles in nanoparticle bulks. The methods of synthesis of semiconductor core/shell nanoparticles in a solution are discussed.
