FIG. 1.

Schematic of the procedure used for synthesis of mixed nanoparticle films where sections of the setup are described as follows: 1, evaporation furnace; 2, aerosol charger 3, DMA in which the voltage controls the size; 4, sintering furnace; 5, particle counter; and 6, film deposition. Stages of the synthesis are described as follows: A, polydisperse SnO particles; , polydisperse Ag particles; B, charged SnO particles, , charged Ag particles; C, size-selected SnO particles; , size-selected Ag particles; D, size-selected particles; N, concentration of particles, , concentration of Ag particles; and E, particle film.
