ABSTRACT

The synthesis of CdTe nanoparticles using CdCl₂ and TeO₂ solutions under the action of laser radiation was experimentally studied. The radiation source was a pulsed Nd:YAG laser with built-in generators of the 2nd and 3rd harmonics, designed to generate radiation with a wavelength of 1064, 532, and 335 nm. The laser pulse duration was 10 ns with an energy of 135 mJ per pulse. In a colloidal solution, the formation of nanoparticles with a diameter of 10 to 50 nm was observed. X-ray diffraction analysis established that the crystal structure of the nanoparticles is the same as that of the bulk material (hexagonal). It is shown that the photoluminescence emission of the obtained nanoparticles has a green color (~510 nm) and is associated with the radiative recombination of free excitons.

Keywords: CdTe nanoparticles, laser ablation, photoluminescence.
