Abstract

InSe and ZnO nanoparticles and, on their base, InSe/ZnO nanoheterostructures are synthesized by laser ablation in a liquid, and their optical properties are studied. The ablation is carried out in a quartz cell with distilled water using an Nd:YAG laser with λ = 1064 nm, pulse duration 10 ns, pulse energy 135 mJ, and repetition frequency 10 Hz for ~10 min. To form the InSe/ZnO nanoheterostructures, InSe nanoparticles are first synthesized and, then, ZnO nanoparticles are synthesized in a colloidal InSe solution. The core/shell colloidal InSe/ZnO solution consists of a core from low energy-gap InSe semiconductor coated with a shell from a higher energy-gap ZnO semiconductor. The optical absorption and luminescence spectra of InSe, ZnO, and InSe/ZnO nanoheterostructures are photograph using an M833 automatic double-dispersion monochromator and a Hamamutsu detector capable of record the radiation in the wavelength range from 250 to 2500 nm. The main evidence of obtaining the core/shell nanoheterostructure is a substantial increase in the luminescence intensity at wavelength λ = 576 nm and the absence of the ZnO nanoparticle luminescence peak in the range 300–400 nm. The energy diagram of the core/shell InSe/ZnO nanoheterostructure has been constructed.
