2024年3月15日 · Variations in the coordination environment of Dy 3+ ions were elucidated through direct evidence from X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and Fourier-transform infrared spectroscopy (FTIR) techniques and via indirect parameters, including Judd-Ofelt (J-O) parameters and the yellow-to-blue (Y/B ...

XPS spectra shows the trivalent, tetravalent and divalent nature of Dy, Ti and Se respectively. Further, it also confirms the transfer of charge from Ti to Dy as result of intercalation in TiSe2.

2020年8月1日 · X-ray photoelectron spectroscopy (XPS) was carried out in a SPECS XPS equipment with Al anode and pass energy of 20 eV. The binding energy of C1s was used as reference (284.5 eV). The band gap energy values were estimated from UV–Vis-DRS spectra performed on a UV–Vis-NIR Agilent Technologies Cary 5000 spectrophotometer.

X-ray photoelectron spectroscopy (XPS) suggested presence of both Ce³⁺ and Ce⁴⁺ in CPOS with later in lower fraction.

2009年7月23日 · The present investigation is devoted to the X-ray photoelectron spectroscopy (XPS) analysis of the main core levels (C 1s, O 1s, Dy 4d, Dy 3d) of a representative dysprosium(III) oxide thin film. The specimen was grown on Si(100) at 500 °C by metal organic chemical vapor deposition (MOCVD) starting from Dy((iPrN) 2 CNMe 2 ) 3 in an N 2 /O 2 ...

2021年11月1日 · The Eu ions were mainly in the 2-valent state and the Dy element was in the 3-valent state in the phosphor, as shown by the XPS data. The fitting results of the afterglow profile showed that the doping of Dy 3+ into the Eu 2+: Sr 2 B 5 O 9 Cl system could significantly enhance the afterglow performance. The TSL results indicated that the ...

The XPS spectrum of Dy 3+ is presented in Figure 4 b, and the XPS peaks at 1304.33 eV and 1336.85 eV are attributed to the Dy 3d 5/2 and 3d 3/2 states, respectively. Additionally, the...

2012年8月4日 · The XPS spectrum in Fig. 9 shows that the Dy 3d 5/2 peak was at a higher binding energy than the theoretical peaks for Dy metal and Dy 2 O 3. Theoretically, the Dy 3d 5/2 peaks for metallic Dy and Dy oxides are at 1295.8 and 1289.0 eV, respectively [ 26 ].

Primary Peak (XPS Signal) used to measure Chemical State Spectra: Dy (4d 5/2) at 152 eV Recommended Pass Energy for Measuring Chemical State Spectrum: 40-60 eV (Produces Ag (3d 5/2 ) FWHM ~0.7 eV)

Dysprosium (Dy³⁺)-doped tin oxide (SnO2) nanoparticles (NPs) have been successfully synthesized using the chemical polymer precursor method. This material blends the holding matrix’s...
