X-band EPR measurements on Mn2+-doped single crystals of Zn (CH3COO)2 ·2H2O, Mg (CH3COO)2 ·4H2O, and Ni (CH3COO)2 ·4H2O have been performed at room, liquid-nitrogen, and liquid-helium temperatures. The spin-Hamiltonian parameters are estimated by the use of a rigorous...
Experimental EPR results of 99.5%[x B2O3(1-x) Bi2O3]0.5%MO glass samples (MO = MnO, Fe2O3 and 0.07 ≤ x ≤ 0.8) systems are presented. The resonance absorptions are centered at g ≈ 4.3 and g ≈ 2.0. For manganese-doped samples both lines show hyperfine structure for certain va...
活性物质鉴定: 采用探针实验、自由基捕获实验和EPR测试识别了压电/Mn3O4-CN/亚氯酸盐体系内的活性物质,该体系存在·O2-、h+、 e-、1O2、·OH、Mn(IV)和ClO2七种活性物质,且与单纯的压电体系和单纯的亚氯酸盐体系相比,该体...
High-frequency EPR spectroscopy on a single crystal displays signal splittings indicative of quantum superposition/entanglement of the two SMMs, and parallel studies on MeCN/toluene (1:1) frozen solutions reveal the same spectral features. The dimer thus retains its structure and inter-Mn3 coupling ...
The EPR spectra of ${\\\mathrm{Fe}}^{3+}$ and ${\\\mathrm{Mn}}^{2+}$ in the single crystal Zn${\\\mathrm{Ga}}_{2}$${\\\mathrm{O}}_{4}$ have been measured. The room-temperature spin-Hamiltonian parameters of ${\\\mathrm{Fe}}^{3+}$, w... JJ Krebs,GH Stauss,...

Otherwise, the EPR comparative experiment of Mn3Gd7(SiO4)6O1.5 and Mn3Gd5.5Ce1.5(SiO4)6O1.5 is shown in Fig. 4(e). Obviously, the peaks of Mn3Gd5.5Ce1.5(SiO4)6O1.5 is higher than that of Mn3Gd7(SiO4)6O1.5, also verifing that the doping of Ce increases the oxygen ...
The organic–inorganic hybrid perovskite compounds have been extensively studied since the dawn of a new era in the field of photovoltaic applications. Up to now, perovskites have proven to be the most promising in terms of power conversion efficiency; however, their main disadvantages for use in...
