| Abstract [eng] |
Thin sulfur layer is formed by using polythionic acids, thiourea, sodium tiosulfate, melted elemental sulfur as sulfuration precursor. In this research crystals of elemental sulfur dispersed in acetone is used. This suspension placed on glass plate and heated up in heating furnace. Copper sulfide coatings obtained by treatment in Cu (II/I) salt solution glass plate with sulfur layer. The amount of CuxS increases with prolongation of the treating time in copper (II/I) salt solution and increasing of solution temperature. Mo – Cu – S coatings on glass obtained by treatment samples with CuxS in Mo(IV) salt solution. The amount of molybdenum increases with the prolongation of the treatment time in copper (II/I) salt solution, when in the coatings are more copper sulfides which could react with Mo(IV) ions. Scanning electron microscopy analysis shows the smoothness of coatings. The surface is unequal and has many small grains. When the treatment in Cu (II/I) salt solution prolonged the surface is more equal. X – Ray photoelectron spectroscopy studies show the chemical composition of obtained coatings. There are MoS2, CuSO4, Cu(OH)2, CuMoS2 in the coatings. Also in the coatings left non-reacted sulfur. X – Ray diffraction studies show the phase composition of the samples. There are elemental sulfur, MoS2, MoO3, copper sulfides – anilite Cu7S4, djurleite Cu31S16 and Cu1.8Mo6S8. After annealing in inert atmosphere in the samples where isn‘t MoO3 and there are a lot of MoS2, anilite and copper – molybdenum sulfide. Optical characterization shows that coatings are composed of copper and molybdenum sulfides and have optical properties of CuxS and MoS2. |
