Abstract. Low-resistance and high-resistance single crystals of Ag3In5Se9 compound have been grown using the methods of zone recrystallization and slow cooling at a constant gradient of temperature. We have investigated spectral and lux-ampere characteristics of photoconductivity and determined the mechanism of recombination inherent to non-equilibrium current carriers. It has been ascertained that the capture of electrons emitted by donor centers is caused by a strong electric field applied to a sample.

Keywords: single crystal, Ag3In5Se9, thermostimulated current, photoconductivity, luxampere characteristic, recombination.
