A study of sonochemically synthesized ZnS:Mn nanoparticles is presented. The particles prepared at low rf power (about 20~W) and room temperature coalesce to form morphologically amorphous large species (30-100~nm in diameter). As the power is increased in the range from 20 to 70~W, and the solution temperature is raised to 60 to 80 <span class='mathrm'><sup>¸</sup>irc</span>C, finer particles are produced with the size ranging from 2 to 20~nm and improved crystallinity. The results indicate the dispersion of the Mn2+ ions at near-surface sites in the particles. It is shown that the sonochemically fabricated particles approach the quality of the ones obtained by a standard chemical route and show a reasonable luminescence performance.
