متن کاملInvestigation of Co nanoparticles with EXAFS and XANES
3, 5, and 12-nm Co nanoparticles were synthesized via thermo-decomposition. Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) were used to probe the structures of these nanoparticles. Simulations were carried out to compare the EXAFS profiles of three different crystalline phases of Co. The results of EXAFS and XANES suggested that the reactivity ...

متن کاملAnalysis and simulation of the structure of nanoparticles that undergo a surface-driven structural transformation.
A room temperature solid-state structural transformation was observed in 3 nm ZnS nanoparticles in methanol following the addition of water (Zhang et al., Nature 424, 1025, 2003). Experimental wide angle x-ray scattering (WAXS), x-ray absorption near edge structure (XANES) and extended x-ray absorption fine structure (EXAFS) spectroscopy measurements show a large increase in crystallinity assoc...
متن کاملDegradation and local distortions in electroluminescent ZnS:Cu,Cl phosphors
We present time-lapsed microscopy and EXAFS/XANES data on size selected ground ZnS:Cu,Cl and ZnS:Cu,Mn,Cl phosphors to probe long standing problems in using these phosphors in high brightness applications. The time-lapsed study shows that many of the individual emission centers on each particle degrade via large step decreases while < 50% have a monotonic decrease. These large steps suggest a b...
