Table 3 presents good conformity of the interplanar spacings evaluated from HRTEM images of SbSI-type nanowires with the XRD data of bulk crystals.…”

“…3. Typical SEM micrographs of xerogels of SbSI sonochemically prepared in ethanol (a after (Starczewska et al, 2008)) and methanol (b after (Starczewska et al, 2009)) as well as xerogels of SbSeI (c after (Nowak et al, 2009b)) and SbS 0.5 Se 0.5 I (d after (Nowak et al, 2010b)) sonochemically prepared in ethanol…”

“…21. Comparison of (a) IR absorbance spectra (without the background): -SbSI ethanogel as prepared, --powdered SbSI single crystals embedded in KBr, ··· KBr alone (after (Starczewska et al, 2008)); (b) IR absorbance spectra of the SbSI ethanogel as prepared (-) and the spectra of ethanol (···) (after (Starczewska et al, 2008)); (c) Comparison of the IR absorbance spectra of the SbSI methanogel as prepared (-) with the spectra of methanol (--) (after (Starczewska et al, 2009)); All spectra were recorded at 300 K.…”

“…22. Comparison of the IR absorbance spectra (without the background) of the SbSI ethanogel (a after (Starczewska et al, 2008)) and SbSI methanogel (a after (Starczewska et al, 2008)) heated to different temperatures: -as prepared, --dried in vacuum (10 -4 mbar) at T=353 K, ··· annealed in vacuum (10 -4 mbar) at T=393 K. Drying and annealing were performed during 8 hours. All spectra were recorded at 300 K Generally, in the case of SbSI nanowires sonochemically prepared in ethanol, the IR bands can be attributed to the vibrations inside the adsorbed C 2 H 5 OH molecules, C 2 H 5 O species, C 2 H 4 molecules, OH groups, and H 2 O molecules (Table 10).…”
