THIN FILMS OF LEAD MOLYBDATE: OBTAINING AND PROPERTIES
Regularities of lead molybdate thin films synthesis were considered, obtained by ion beam sputtering. The process of thin films synthesis by sputtering with two ion beams is considered. This technique allows independent targets sputtering of two reactive components (lead oxide PbO and molybdenum trioxide MoO3) with formation of gaseous streams of particles that come to the surface of the substrate, where the synthesis of lead molybdate takes place. Grown PbMoO4 thin films were oriented, polycrystalline and had the structure of scheelite. The model of PbMoO4 layers formation on the surface of fused silica SiO2 is discussed. The analysis of growth processes is provided. X-ray analysis of samples using scanning probe atomic force microscope MultiMode 8 was conducted. Research has shown that the formation of PbMoO4 thin films is a complex physical- chemical process that is proved by the experimental data being compared with the theoretical ones.
