Magneto-optical study of the I2 bound exciton in ZnTe

The 1L0-phonon replica of the I₂ bound exciton in ZnTe at 2.374 eV is fully resolved into a quintet at fields of 130 kG. Analysis of the data shows that the I₂ complex consists of an exciton bound to an $\text{ionized}$ donor or acceptor; the electron and hole gyromagnetic ratios deduced, $\text{g}{}_{\mathrm{h}}\text{= ? 1.2}$ and g_e = ± 1.7, are in excellent agreement with the values determined from recent spin-flip scattering experiments, viz. g_h = 1.07 ± 0.1, g_e = 1.74 ± 0.05.
