When the temperature is raised to 540 ◦C, there is an obvious change in the surface morphology of the grains (Figure 7c), whereby the grain size increases markedly to 1.0–1.5 µm and the CMZTSSe film presents a very smooth and dense state, implying enhanced crystallization due to ...
A d3 Mn(IV) ion in an octahedral symmetry has a ground state 4A2g and should show an isotropic resonance on its ESR spectrum with g < 2 value [76,77]. Since the four manganese ions in 1 do not have perfect octahedral geometries, they instead show tetragonal distortion and the spin-...
