various architectures of colloidal cu3(moo4)2(oh)2 and cu3mo2o9; thermal stability, photoluminescence and magnetic properties of cu3(moo4)2(oh)2 and cu3mo2o9 nanosheets

The lindgrenite compounds, with the chemical formula cu3(moo4)2(oh)2, exhibiting diverse architectures and high crystallinity, were synthesized using a straightforward surfactant -assisted hydrothermal method. subsequently, cu3mo2o9 samples were produced by calcining the synthesized cu3(moo4)2(oh)2 precursor. these samples demonstrated excellent crystallinity, colloidal characteristics, high yield, and scalability, making them suitable for large-scale production. the synthesis utilized non-toxic and cost-effective reagents, with water serving as an environmentally friendly solvent. scanning electron microscopy revealed that the lindgrenite nanostructures were well-crystallized and featured rod-like, sheet-like, and hollow sphere morphologies. specifically, the products comprised cu3(moo4)2(oh)2 rods with diameters of approximately 100 nm, nanosheets with thicknesses ranging from 30 to 100 nm, and hollow spheres composed of numerous nanosheets measuring approximately 40 to 70 nm in thickness. thermal treatment of lindgrenite preserved the original morphologies in the formed cu3mo2o9 samples. additionally, the nanosheet samples exhibited superparamagnetic behaviour at room temperature, as evidenced by their photoluminescence and magnetic properties. compared to previous studies, the cu3(moo4)2(oh)2 and cu3mo2o9 samples synthesized via the surfactant-assisted hydrothermal method displayed a notable red-shifted photoluminescence emission with high intensity.
