研究目的
To synthesize and characterize a series of lanthanide-containing germanotungstates and investigate their photoluminescence and electrochemical properties.
研究成果
A series of six tetrameric lanthanide-containing germanotungstates were synthesized and characterized. The compounds showed good photoluminescence properties and were isostructural, belonging to a triclinic crystal system with space group P1. The electrochemical properties of the complexes were also studied.
研究不足
The study was limited to six lanthanides (Sm, Eu, Gd, Tb, Dy, Ho), and the reactions with other lanthanides under the same conditions resulted in carbonate encapsulated sandwiched compounds or precipitates.
1：Experimental Design and Method Selection:
The synthesis involved the reaction of trilacunary Na10[A-α-GeW9O34]?16H2O with lanthanide nitrate salts in
2：5 M potassium chloride solution under ambient conditions. Sample Selection and Data Sources:
Lanthanide nitrate salts (Sm, Eu, Gd, Tb, Dy, Ho) were used.
3：List of Experimental Equipment and Materials:
FT-IR spectroscopy, SC-XRD, UV/Visible spectroscopy, TGA, electrochemistry, ESI-MS, PXRD, and photoluminescence equipment were used.
4：Experimental Procedures and Operational Workflow:
The interaction of the precursor with lanthanide salts led to the formation of tetrameric structures, which were then characterized using various analytical techniques.
5：Data Analysis Methods:
The data were analyzed using standard techniques for each characterization method.
