Witrynaphase diagram of Fe-implanted ZnO is rather well established (continuous part of the arrow in figure1), both in terms of structure and magnetism, the magnetic behavior of the Fe impurities in single-phase Zn1xFexO is still poorly understood (dashed part of the arrow in figure1, i.e. regions (1) and (2)). WitrynaCathodoluminescence (CL) microscopy of Ni/cubic-ZrO2 nano–composites has been used to demonstrate the presence of both secondary phases and compositional fluctuations within the microstructure. X-ray microanalysis showed that in this material red CL emissions were generated from aluminium rich phases, blue emissions originated …
