“…by breakage of P−O−P bridges using the oxygen of the modifier oxide. The O DB and O NB cannot be differentiated in the PO 4 tetrahedra [14]. The position of the P−O peak at ~0.153 nm (table 1) is of the same magnitude as the mean bond lengths found for other binary phosphate glasses [28,38].…”

“…P−O−P bridges are not expected for the glasses with low P 2 O 5 contents [13,14]. A variety of lengths of P−O bonds in P−O−Ge bridges can arise from links with the different GeO 4 , GeO 5 and GeO 6 units.…”

“…Metal phosphate glasses are extensively studied due to the fact that they present non-linear optical, magnetic and electrical conductivity properties that provide them with several technological applications such as optical fibers with low loss, waveguides, laser glasses, and others [1][2][3][4]. Since pure phosphate glasses are unstable, antimony oxide is incorporated, providing enhanced chemical stability [5].…”

“…Slight shoulders may be a consequence of overlapping peak positions and variable intensities [35][36][37][38] . Figure 36,40 . B2: P40 showed deconvolution of the P 2P 3/2 and 1/2 high-resolution spectral peaks, specifically the P 2p 3/2 and P 2p 1/2 spin orbitals at 134.4 and 133.5 eV, attributed to (P2O7) 4-and (PO4) 3-41 42 .…”

This factor led to highly soluble coatings, exhibiting a t 1/2 degradation dependence in the first 2 hours in distilled water, followed by a more characteristic linear profile as the subsequent layers were less soluble. Hydration and degradation was observed to preferentially occur, forming voids characteristic of pitting corrosion which was confirmed by use of a Focused Ion Beam. Coating degradation in PBS precipitated a (PO3) -metaphosphate, X-Ray amorphous layer, which remained adherent to the substrate and seemingly formed a protective diffusion barrier which inhibited further coating degradation.The implications are that whilst compositionally similar, sputter deposited coatings and melt quenched glasses are structurally dissimilar, most notably, with regards to the surface layer.This factor has been attributed to surface etching of the as deposited coating layer during 2 deposition and variation in the thermal history between the processes of magnetron sputtering and melt quenching.
