Ga K-edge EXAFS analysis on the coordination of gallium in PbO–Ga2O3 glasses

Spatial distribution of rare-earth ions in Se-based chalcogenide glasses with or without Ga

“…Measurements in the photon energies of below and above Ga Kedge were carried out in the transmission mode at room temperature. Related information can be referred to our previous reports [10,11]. UWXAFS software package was used for data reduction and least-squares curve fits of the experimental EXAFS spectra with a Ga-Se pair EXAFS spectrum generated ab-initio theoretically by the FEFF8 code [12,13].…”

Chemical characteristics of Dy–S bonds in Ge–As–S glass

“…The X-ray absorption measurements were carried out both in transmission and fluorescence modes at room temperature at the Pohang Accelerator Laboratory, Republic of Korea and the Siberian Synchrotron Radiation Center, Russia. Experimental details and the method of analyses using the commercial UWXAFS software package can be found from the previous reports [14][15][16]. A Dy-S pair EXAFS spectrum generated ab initio theoretically by the FEFF8 code was used for optimization of the local structural parameters associated with Dy atoms [17].…”

Visible luminescence characteristics of Dy3+-doped LBTAF glasses

“…The difference between the experimental and calculated lifetimes may be due to multiphonon relaxation and cross relaxation [32]. The estimated multiphonon relaxation rate, using the following equation [33] is 1.53 × 10 3 s −1 .…”
