MORPHOLOGY CONTROL OF ANGLESITE MICROCRYSTALSWITH POLYHEDRON: SYNTHESIS, GROWTH MECHANISM,AND OPTICAL PROPERTIES

摘要

The formation of novel structure polyhedron-shaped PbSO_4 single crystal by reaction of UV-irra-diation and hydrothermal treated method is described. The kinetics of crystallization of PbSO_4 assembly is studied as a function of aging time and reaction time. The possible mechanism is also discussed. The effect on the crystallization of PbSO_4 micro-polyhedron under different conditions is investigated. The optical properties are also studied. The results show that tungstosilicate acid (TSA) acting as catalysts and a new class of inorganic scaffolds for the synthesis of materials in crystal engineering and composites design for different applications is versatile reactor and may be extended to the creation of other highly novel inorganic structures with applications in catalysis, novel optical materials and other fields.
