Abstract

Synthesis of zinc sulfide as luminescence pigment was obtained by precipitation method from zinc oxide and natrium sulfide materials. Zinc chloride as precipitate solution was prepared from leaching product between zinc oxide and HCl. Furthermore, natrium sulfide was added to obtain ZnS with various mass of  10, 20, 30, and 40 g. The precipitation product was heated at temperature 200°C for 2 hours and then it was calcined by direct firing technique. Visual characterization under UV lamp has gained the highest intensity of luminescence at sampel with varying mass of 10 g  natrium sulfide. X-Ray diffraction anlysis indicates the best peak of ZnS phase at sampel with varying mass of 30 g  natrium sulfide at diffraction angle 28,5°. The diffraction intensity rapidly decreases with decreasing of natrium sulfide mass. Synthesis of nanoparticle ZnS using this method was effective to produce luminescence material. In fact that the luminescence pigment are import material, so that this result are the excellent candidate for the luminescence pigment application such as a document security, money security, etc.
