Abstract
The authors report the synthesis of nanocrystalline, alloyed PbEuS, a potentially important dilute magnetic semiconductor. The thermolysis of mixed precursors has been adapted for the formation of homogeneous alloyed nanocrystals. X-ray diffraction and magnetization measurements of ternary PbEuS nanocrystals provide convincing evidence that no phase separation occurs in these nanomaterials for europium concentrations up to x = 0.17. X-ray photoelectron spectroscopy provides the atomic composition for PbEuS alloy nanocrystals juxtaposed with the ratio of the starting precursors.
