quenching. Also it should be noticed that the real content of Mn2+ for the same nominal Mn2+ contents in Fig. 5b,d should be not actually the same due to the preferred occupancy of Yb3+ ions and the cation-cation repul- sion in zeolite. This is also the cause of different emission...
In polyanion cathodes, the inductive effect alters the potential of a M(n+1)+/Mn+ redox couple (M − transition metal) according to the electronegativity of the X cation in the polyanion groups (XO4m+). To manipulate the operating potential, we synthesized a series of mixed sulfate...
The cation is K, and the anion is F, write the name and chemical formula. Please give the names of the following compounds. Write the name and formula of the compound formed between H+ and CO32- ions. Write the name and formula of the compound formed between H+ and ClO4- ion...

Here we present an in-depth study of the magnetic properties of a family of metal–organic perovskites ABX3, [CH3NH3][M(HCOO)3] in which A = CH3NH3+ is the methylammonium cation, B = M is a divalent metal cation (Mn2+, Co2+, Ni2+ or Cu2+), and X is the formate anion (H...
The group-IIB cation in chalcopyrite structure is surrounded by a tetragonally distorted anion (i.e., P3− ion here) tetrahedron [11]. The tetragonal distortion is related to a clockwise and counterclockwise rotation of anion tetrahedron by an angle ±τII about [0 0 1] axis [11]. From...
The IR and Raman spectra confirm the presence of the ethylenediammonium cation and phosphite anion. The diffuse reflectance spectrum is in accordance with the presence of Co(II) and Mn(II) high spin cations in slightly distorted octahedral symmetry. The calculated Dq and Racah parameters for the ...
