Solution routes to SnE, and PbxSn1-xE [E= S, Se, Te] nanoparticles are of interest for bioimaging and solar panels due to their size-tunable infrared properties. To explore the influence of precursor selection on morphology and phase, SnE and PbxSn1-xE  particles were prepared using solution precipitation or solvothermal routes and various tin carboxylates: Sn(OCCH3)2 (1 ), Sn(O4C2)2 (2 ), Sn(O2C(C2H5)CH(CH2)3CH3)2 (3 ), and Sn(O2C(CH2)7CH=CH(CH2)7CH3 (4 ), and chalcogenides (S, Se, and Te) were used. The yield was characterized with X-ray Diffraction and Transmission Electron Microscopy. Through these synthetic routes, we have prepared nanosheets and particles with various phases of SnO, SnSe, SnTe, and PbxSn1-xE. This work was supported by the Laboratory Directed Research and Development (LDRD) program at Sandia National Laboratories.  Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.
