1. The spectrum of the clean alumina surface prior to adsorption is shown as Fig. 1a for comparison. Three IR peaks in the OH stretching area are observed at 3730, 3678, and 3589 Behavior of CF2H–CH2–OH adsorbed on Al2O3 at 100 K At 100 K, 2,2-difluoroethanol appears to be...
FT-IR spectroscopy which gives the presence of an absorption band corresponding to the stretching mode frequency of ZnO (ZnO), the bands corresponding to organic precursors were no longer present in the FTIR spectrum after doping, which supports the incorporation of Yb ions into the ZnO lattice....
infrared spectrumglass transition temperatureThe FTIR spectra of heavy metal oxide doped borate glasses with the general formula RO-MO-B2O3 (RO= MgO, CaO, SrO and BaO, MO=ZnO, TeO2, PbO and Bi2O3) were studied in the spectral range 400-4400cm-1 toobtain information about the influence ...

Although the sensitization process did not cause the appearance of any intense new peak in the FTIR results, the traces of a new band at 756cm1and also the intensification of the peak at 3411cm1(in comparison to ZnO spectrum) confirmed the formation of some new bands between NPs and VB12...
