in the present study, silver oxyfluoride modified silver electrode was employed to electrocatalytic oxidation of isoniazid. the process of oxidation and its kinetics were established by using cyclic voltammetry, chronoamperometry and amperometry techniques. the modified electrode shows a stable and linear response in the concentration range of 3×10−4 to 2.1×10−3 mol l-1 with a correlation coeff...

Metal oxyfluorides constitute a broad group of chemical compounds with rich spectrum crystal structures and properties. Surprisingly though, none the ternary contains cation from 11 periodic table. Intending to find one, we focused on silver derivative, Ag2OF2 system, which may be considered as 1:1 “adduct” AgF2 (i.e., an antiferromagnetic positive U charge transfer insulator) AgO diamagnetic d...

This work reports the mid-infrared emission properties around 2 μm in Ho/Yb codoped germanate glasses. The glass not only possesses good chemical durability and good thermal stability but also has high midinfrared transmittance around 2 μm (90%). In addition, the glass possesses considerably low OH content (20.45 ppm) and large spontaneous transition probability (103.38 s) corresponding to the ...

Bulk oxyfluoride glasses doped with Ag nanoclusters have been prepared using the melt quenching technique. When pumped in the absorption band of Ag nanoclusters between 300 to 500 nm, these glasses emit a very broad luminescence band covering all the visible range with a weak tail extending into the near infrared. The maximum of the luminescence band and its color shifts to the blue with a shor...
