摘要：
Luminescence and photoconductivity of layered Cu3In5S9 crystals at high levels of optical excitation are studied experimentally. A pulsed nanosecond Nd:YAG laser with built-in second and third harmonic generators to generate 1064-, 532-, and 355-nm radiation is used as a light source. It is found that the photoluminescence spectra exhibit two emission bands due to zone-acceptor level and impurity donor-impurity acceptor transitions. It is shown that the photoconductivity in Cu3In5S9 is monopolar. The waveform of the photoconductivity consists of fast and slow components associated with two channels of recombination.
