Iron doping effect on the electronic structure in yttrium aluminosilicate glasses

Theoretical studies of the optical and EPR spectra for Fe3+ ion in the MF3:Fe3+ (M=Al, Ga) systems

“…This means that the expansion effect in A1F 3 :Fe 3 + is stronger than that in GaF 3 :Fe 3 + system. As for the distortion angle, we can see that Dy=0.8001 for A1F 3 :Fe 3 + system is close to the value Dy=0.9401 for GaF 3 :Fe 3 [22], respectively. Of course, careful experimental investigations especially ENDOR experiment are required in order to clarify the local distortions around the Fe 3 + in A1F 3 :Fe 3 + and GaF 3 :Fe 3 + systems in detail.…”

“…Fluoride glasses have emerged as the material of choice for optical fiber amplifiers and fiber lasers and quickly became of major interest for telecommunication application [1][2][3][4]. Especially, metal fluoride glasses based on GaF 3 , A1F 3 , ZnF 2 , InF 3 etc., which present a high optical transparency in the mid-infrared, have been extensively applied in optical sensors, fiber laser, optical amplifier, optical fibers [5][6][7], etc.…”

Effective solar-based iron oxide supported HY zeolite catalyst for the decolorization of organic and simulated dyes

“…Both of the binding energies are similar to the reported values of 710.5 and 724.1 eV for Fe 2p in a-Fe 2 O 3 . 32 However, the observed values for the catalyst materials were slightly shifted to higher binding energies compared to the pure metal oxide, which suggests a strong interaction between 36 The XPS spectra of Fe 2p and O 1s indicated that the valence states of Fe and O are +3 and À2, respectively.…”

Synthesis and characterisation of a new composite aluminosilicate bioceramic

“…Aluminosilicate glasses containing radioactivable isotopes like yttrium and dysprosium attracted interest for in situ radiotherapy [3,4] because the glasses containing initial stable isotopes can be activated by neutron irradiation. The advantage of using these radiation carriers in relation to the conventional external beam radiotherapy is that much larger doses of radiation can be safely delivered to the target site, and the exposure of other parts of the body is diminished.…”
