Claim:
1. A method for synthesizing a Bi 2 Te y Se 3-y thermoelectric nanocompound (0<y<3), comprising the following steps: preparing a Bi—Te—Se solution by adding Bi, Te, and Se precursors to a solvent (step 1); preparing a hydrate by mixing the Bi—Te—Se solution prepared in step 1) with a base aqueous solution (step 2) until a pH of 7.0 is reached; preparing a Bi aging the Bi preparing Bi wherein the solvent of step 1) is a nitric acid aqueous solution, wherein the nitric acid is provided in stoichiometric excess compared to the Bi, Te, and Se precursors, and wherein step 1) through step 4) are performed at room temperature.
