METAL TELLURIDE NANOCRYSTALS AND SYNTHESIS THEREOF |
摘要 |
A process for synthesizing a metal telluride is provided that includes the dissolution of a metal precursor in a solvent containing a ligand to form a metal-ligand complex soluble in the solvent. The metal-ligand complex is then reacted with a telluride-containing reagent to form metal telluride domains having a mean linear dimension of from 2 to 40 nanometers. NaHTe represents a well-suited telluride reagent. A composition is provided that includes a plurality of metal telluride crystalline domains <?in-line-formulae description="In-line Formulae" end="lead"?>(PbTe)<SUB>1-x-y</SUB>(SnTe)<SUB>x</SUB>(Bi<SUB>2</SUB>Te<SUB>3</SUB>)<SUB>y</SUB> (I)<?in-line-formulae description="In-line Formulae" end="tail"?> having a mean linear dimension of from 2 to 40 nanometers inclusive where x is between 0 and 1 inclusive and y is between 0 and 1 inclusive with the proviso that x+y is less than or equal to 1. Each of the metal telluride crystalline domains has a surface passivated with a saccharide moiety or a polydentate carboxylate. A densified mass having a density of greater than 95% of the theoretical density includes a plurality of lead telluride, tin telluride, bismuth telluride, or a combination thereof of domains having a mean linear dimension of from 2 to 40 nanometers inclusive that have been subjected to hot isotactic pressing.
