| Popis: | 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. |
