Abstract:
1. A method of production of a nanocomposite thermoelectric conversion material comprised of a Bi 2 (Te 1-x ,Se x ) 3 thermoelectric conversion material (where 0≦x<1) as a matrix in which ceramic phonon scattering particles are dispersed, the method of production of a nanocomposite thermoelectric conversion material including a step of adjusting a first aqueous solution of a Bi complex to a higher pH value than an isoelectric point of phonon scattering particles, a step of adding phonon scattering particles not modified on their surface to said pH adjusted first aqueous solution, and a step of mixing said first aqueous solution to which phonon scattering particles have been added and a second aqueous solution including Te anions or Te anions and Se anions.
