| 内容記述 | In this study, we prepared an alkaline-earth metal-based pyro-vanadate (Ca2V2O7, Sr2V2O7, and Ba2V2O7) that exhibits white fluorescence and observed by photoelectron spectroscopy for the purpose of analyzing its electronic state and revealing differences in the electronic states of the three samples. The measurement was carried out by correcting the charge on the sample's surface using a neutralization system at the time of measurement because the samples were insulators. As a result, it was confirmed that all the three samples produced this time were insulators, because fitting was possible with symmetrical peaks in all the measured peaks. At the point of analysis, Ca2+, Sr2+ and Ba2+ ion was confirmed in Ca2V2O7, Sr2V2O7, and Ba2V2O7 because the s orbital spectra of Ca, Sr and Ba in each samples could be fitted with one peek. In addition, V5+ ion was confirmed in the three samples because their V 2s spectra could be fitted with one peak. As a result of comparing the valence band spectra of the three samples, it was found that there was a difference in the peak shape of the V 3d and O 2p hybrid orbitals found near the fermi level. When comparing Ca2V2O7 and Sr2V2O7, it was found that the intensity of Sr2V2O7 was lowered per 2 to 5 eV, in addition, comparing Ca2V2O7 and Ba2V2O7, the intensity of Ba2V2O7 was lowered per 5 to 7 eV. Therefore, there were slight differences in the electronic states of the three samples. As a result of comparing the V 2s and V 2p (3/2) spectra of the three samples, there was a slight difference in the peak position, but no significant difference in the peak shape. | |||||||||
