چکیده
EPR spectra of Ho 3+ impurity ions were recorded in single crystals yttrium aluminum garnet (Y 3 Al 5 O 12 ) the frequency range 114-170 GHz, at a temperature 4.2 K. The measurement results indicate substitution for Y dodecahedral position with D 2 local symmetry. magnitude g-factor, hyperfine structure constant, and energy interval between main first excited nondegenerate sublevels multiplet I 8 are determined. Weak satellite signals have also been registered, origin which is associated formation antisite defects environment paramagnetic centers. Keywords: interaction, rare earth ions, spin Hamiltonian, non-Kramers ion.

A three-dimensional (3D) mesoporous Fe2O3−CdS nanopyramid heterostructure is developed for solar-driven, realtime, and selective photoelectrochemical sensing of Cu in the living cells. Fabrication of the mesoporous Fe2O3 nanopyramids is realized by an interfacial aligned growth and self-assembly process, based on the van der drift model and subsequent selective in situ growth of CdS nanocrystal...

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...

The background electrogenerated chemiluminescence (ECL) emission observed only upon electrochemical oxidation of tri-n-propylamine (TPrAH) on a platinum electrode is a limiting factor in ECL analytical techniques and is poorly understood. We studied this reaction in aerated acetonitrile (MeCN) solution with TPrAH oxidized at a constant potential at the Pt surface and observed ECL spectra with a...
