摘要：
High resolution reflectance spectroscopy experiments were performed to study the Zn 3d states of Zn1-xMnxS over the whole concentration range (0 less-than-or-equal-to x less-than-or-equal-to 0.56). For zincblende-type samples (x < 0.05), we observe the excitation of three core level excitons reflecting the threefold split Zn 3d states at the GAMMA-point. The splitting of the GAMMA5 state due to spin-orbit interaction is DELTA(so) = 251 meV. For the core exciton binding energy, a value of 517 meV is determined. For wurtzite-type samples (x > 0.05), the core exciton derived structures are broadened, reflecting the tenfold splitting of the 3d states under C6v symmetry.
