摘要
The set of four ternary coordination compounds of terbium were prepared with diketone 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione (TFDH) and four different neutral ligands (L) having an overall formula [Tb(TFDH)3L]. Resulting compounds were characterized using different techniques including NUV absorption studies, photoluminescence (PL) spectroscopy, electrochemical and thermal analyses. PL spectra confirmed the green luminescence of synthesized complexes by giving characteristic dominant 5D4 → 7F5 peak around 545 nm. Electronic and optical energy gap values lying ∼3.5 eV reveals their potential to use in semiconductor materials. All the spectral results are in good harmony with each other and highlight their functionality in lighting, biomedical imaging and sensors etc.
