Abstract

We report the synthesis and characterization of nanocrystalline Pb _xEu _yS, a potentially important dilute magnetic semiconductor. The thermolysis of mixed precursors was adapted for the formation of homogeneous alloyed nanocrystals. Energy dispersive spectroscopy provided the atomic composition for Pb _xEu _yS nanocrystals, which we juxtaposed with the ratio of the precursors. X-ray diffraction and magnetization measurements of the nanocrystals provided evidence that no phase separation occurred for europium concentrations of up to y = 0.15.
