Single crystals of CuInS2 were studied with reflectance (RF) and photoluminescence (PL) at 4.2 K in magnetic fields up to 10 T. The diamagnetic energy shifts observed for the free excitonic lines in both the RF and PL spectra were used to calculate the reduced masses (0.141m0, 0.142m0, and 0.114m0), binding energies (18.46, 18.59, and 14.90 meV), Bohr radii (3.82, 3.79, and 4.73 nm), and hole effective masses (1.20m0, 1.28m0, and 0.40m0) for the ALPB, AUPB, and BC excitons, respectively, using a low-field perturbation approach.
