“…The large peak with an isomer shift ( δ ) close to 0.0 mm s −1 is ascribed to Sn IV because this δ is typical for Sn IV . The doublets observed in the region 2–6 mm s −1 are ascribed to Sn II from their δ values 13. The relative amounts of the various Sn species are obtained from the 4.2 K data by integration of the areas of the curves used for fitting.…”

“…The doublets observed in the region 2-6 mm s À1 are ascribed to Sn II from their d values. [13] The relative amounts of the various Sn species are obtained from the 4.2 K data by integration of the areas of the curves used for fitting. Both room temperature as well as 4.2 K Mçssbauer data for Sn-TiO 2 -Y revealed the presence of tin in two oxidation states, Sn II and Sn IV , whereas for the Sn-TiO 2 -W the spectrum showed only Sn IV .…”

During our exploration of compounds in the Sn(II)-Ti(IV)-O system, we discovered that hydrolysis of titanium alkoxide solution in the presence of Sn(II) salts resulted in stable deep-yellow colored anatase nanoparticles. The samples were characterized by X-ray powder diffraction, electron microprobe, thermal analysis, transmission electron microscopy, and (119)Sn Mössbauer spectroscopy. Mössbauer data of the yellow colored samples showed the presence of both Sn(II) and Sn(IV) in a distorted environment as expected in the anatase structure. It is suggested that the cationic charge imbalance is compensated by oxygen vacancies and/or hydroxyl groups as evidenced by Mössbauer data which show two types of Sn(II) environments. When heated in air to 300 degrees C the samples changed color to completely white and (119)Sn Mössbauer data of these samples showed only the presence of Sn(IV). These observations indicate that the origin of the yellow color in our Sn doped anatase nanoparticles arises from filled Sn 5s states just above the O 2p band, thus decreasing the band gap. The Sn(II) doped anatase TiO(2) nanoparticles reported here can potentially lead to environmentally benign yellow pigments. The simplistic nature of the synthetic procedure could easily be adapted to large-scale industrial manufacture.

Structure Characterization of Semiconducting Tin and Tungsten Mixed Oxides

Mixed-oxide powders of tin and tungsten were made by heating various mixtures of SnO and powders, corresponding to the nominal formula WO 3 with x between 0.5 and 2.0, in an argon atmosphere at 600 ¡C Sn x WO 3`x for 15 hours. The phase was the result of heating of an equi-a-SnWO 4 molar mixture of SnO and powders. In addition to 119Sn Mo ssbauer WO 3 experiments, X-ray di †raction and Raman spectroscopy were used to study the phase structures of the mixed-oxide powders. Mo ssbauer spectra from all samples show a small peak at D0 mm/s from phase(s) like rutile SnO 2 , and a larger peak doublet centred at D3.4 mm/s from the phase, a-SnWO 4 where tin is in the form Sn4`and Sn2`, respectively. Another peak doublet centred at D3.0 mm/s was needed to obtain reasonable Ðts for samples with x P 1.3. This doublet originates from an undocumented phase where tin is also in the divalent form Sn2`. 119Sn Mo ssbauer spectroscopy made it possible to reveal the relative amounts of the two valence states of tin in the mixed-oxide structures. Raman spectroscopy as the other probe for ""localÏÏ structures was insensitive to reveal the changes in the phase structures between di †erent mixed-oxide samples up to x \ 1.72, but an extra peak at D890 cm~1 in the Raman spectrum from the sample with x \ 2.0 indicates also the presence of the undocumented phase.
