The use of tungsten disulfide dots as highly selective, fluorescent probes for analysis of nitrofurazone.

摘要: Tungsten disulfide (WS2) is a two-dimensional transition metal dichalcogenide, which of particular interest because it has highly anisotropic bonding, leads to strongly electrical and mechanical properties. Thus, in this work, simple hydrothermal process was developed produce photoluminescence from WS2 dots. This achieved the presence sodium tungstate reduced L-glutathione; emitted fluorescence produced quantum yield as high 0.066. The dots associated were investigated with use transmission electron microscopy, atomic force X-ray photoelectron spectroscopy, Fourier transform infrared UV-vis spectroscopies. used fluorescent probe analyze nitrofurazone (NFZ). resonance energy transfer (FRET) mechanism also found be linear range 0.17-166 μmol L(-1) detection limit 0.055 L(-1). proposed method successfully applied for analysis NFZ nasal drops water samples.
