ToF-SIMS of Polyphosphate Glasses
No full textPhosphate glasses have been investigated in detail, due to their interesting optical properties: low dispersion, high refractive index and high transparency for ultraviolet light. More recently, the low processing temperature of zinc and iron phosphates as well as their chemical durability opened the possibility for new applications, such as immobilization of nuclear wastes and biomechanical properties. Polyphosphate glasses have also been investigated for their anti-wear properties, since almost all common engine oil additives contain phosphorus and are able, under sliding conditions, to react on steel surfaces to form a protective tribofilm mainly constituted of glassy polyphosphates The characterization of the surface chemistry of such glasses turns out to be a key step for understanding their mechanism of action.
In this work zinc and iron phosphate glasses of different chain length were synthesized and characterized by means of ToF-SIMS. ToF-SIMS was able to successfully differentiate between the samples of different composition

Characterization of Functional Films on Solid Substrates by Tof-Sims
No full textIn the last few years the creation of functional films on solid substrates has become increasingly attractive in particular with the aim of functioning silicon based-electronic devices with biological molecules. TOF-SIMS is a useful technique to characterize the films at the submicrometer scale because of its surface selectivity and molecular specificity. However the use of TOF-SIMS is limited by the difficulty in the quantification particularly for organic materials. We performed experiments on silicon oxide substrates covered by polysiloxanes to which organic molecules simulating biological molecules («probes») were attached by covalent binding. In the present paper: 1) we show that the fragmentation pattern is dominated by large molecular weight fragments assigned to the probes; 2) we demonstrate by two independent techniques that quantitative information can be extracted from TOF-SIMS data utilising the intensity of the relevant peaks assigned to the probe
