Investigation of obtaining ZnSe nanopowders by means of a fiber ytterbium laser

The production of zinc selenide nanopowder using repetitively pulsed radiation from a ytterbium fiber laser has been studied. With an average radiation power of 300 W and a pulse duration of
$120\ \mu\mathrm{s}$
, the productivity of nanopowder production was ≈100 g/h. The nanopowder contains weakly agglomerated particles that have a spherical shape, as well as the shape of polyhedrons. Their arithmetic average size is 18 nm. Nanoparticles have two crystalline phases: cubic (40 wt.%), and hexagonal (60 wt. %).
