Abstract: A preparation method of even-sized ZnS:Mn nanoparticles is provided to obtain ZnS:Mn nanoparticles having excellent phosphorescence at lower temperature in a simple process economically by employing liquid-solid-solution synthesis method under optimized selections for raw material compounds, Mn concentration and treatment temperature. A preparation method of ZnS:Mn nanoparticles comprises steps of: 1) forming a primary liquid layer by dissolving zinc acetate and manganese nitrate in distilled water; 2) forming a secondary layer by adding linoleate type organic materials to the primary layer; 3) forming a tertiary liquid layer by adding linoleic acid and a solution having thioacetamide in ethanol to the secondary layer; 4) forming ZnS:Mn nanoparticles by treating the prepared primary, secondary and tertiary layers at 85-95deg.C for 9-12 hours; 5) collecting and washing the ZnS:Mn nanoparticles; 6) drying the washed ZnS:Mn nanoparticles; and 7) treating the dried ZnS:Mn nanoparticles at ambient temperature-600deg.C for 9-12 hours. The molar ratio of zinc acetamide in step 1) and thioacetamide in step 3) is 0.9-1.1:0.9-1.1, respectively. The amount of manganese nitrate is 1-10at.% in the solution in step 1). The molar ratio of zinc acetamide and manganese nitrate is 1:0.005-0.02 in step 1).
