抄録

Pressure and temperature dependence of photoluminescence (PL) spectra of ternary compound semiconductor CuAlS<SUB>2</SUB> doped Er and Fe are measured. Under hydrostatic pressures, PL peaks originated in transitions of 4f electrons in Er shift to lower energy and new sharp peaks appears. These results are discussed in terms of crystalline fields and spin-orbit interaction. The broad peak assigned as self-activated (SA) PL shifts to high energy under high hydrostatic pressures which coefficient is the same sign and order as that of band gap of chalcopyrite type I-III-VI<SUB>2</SUB> compounds. This result indicates that SA PL is related to Bloch bands.
