“…Since F -ions can substitute hydroxide or oxygen sites, 18 anodization in the solution containing F -ions may lead to the breakdown of the bonds of Pb-(OH) 2 or Pb-O, resulting in the local etching of PbO.…”

“…For the cubic β-PbF2, each lead ion is surrounded by eight fluoride ions, which are accommodated at the corners of a surrounding cube. 2 It has been demonstrated that α-PbF2 is a strong scintillator that can be used as a detector in electromagnetic calorimeter and β-PbF 2 is a superionic conductor that can be used as a solid electrolyte in Li ion batteries. 3,4 To the best of our knowledge, there are no many reports on the preparation of nanostructured PbF 2 .…”

“…8 More recently, Zhu et al have demonstrated that β-PbF2 microsphere and α-PbF 2 microrods with different size can be controllably fabricated by hydrothermal methods. 2 Anodization technique is based on an electrolytic passivation process that allows increasing the thickness of natural oxide formed on the metal surface, resulting in the formation of corrosion and/or wear resistive oxide. Recently, several groups demonstrated that self-ordered nanoporous oxides can be prepared on various metals such as aluminum, titanium, zirconium, niobium and so on by anodization techniques.…”

In this work, we investigate anodization of Pb in ethylene glycol containing small amount of NH4F, demonstrating that β-PbF2 particles with octahedral morphology can be prepared by adjusting the applied potential and anodizing time. FE-SEM images and XRD measurements of anodic nanostructures as a function of anodizing time clearly show that PbO is first formed on Pb. Subsequently, a local dissolution of PbO leads to formation of skeleton structure of PbO, releasing Pb 2+ ions in the electrolyte. The lead ions can be precipitated on the walls or intersection of the skeleton walls when the concentration of lead ions is saturated. The method described in this article shows the feasibility of formation of metal fluoride crystal by anodization of metal in a fluoride containing solution.

“…Zhu et al successfully prepared α-PbF 2 microrod and microtubes by adjusting CTAB (Cetyl Trimethyl Ammonium Bromide) and acetic acid content, as well as F/Pb ratio. They also found that when F/Pb ratio was less than 4, an α phase PbF 2 [5] was always synthesized. But, there has been no work on the rare earth metals doped α-PbF 2 materials by now.…”

“…Among the recent research work [5][6][7][8], the preparation of α-PbF 2 with various morphology by a simple hydrothermal method at low temperature, seems much more meaningful. Zhu et al successfully prepared α-PbF 2 microrod and microtubes by adjusting CTAB (Cetyl Trimethyl Ammonium Bromide) and acetic acid content, as well as F/Pb ratio.…”
