Optical measurements of bulk GaSb:S reveal the structure of the lattice two phonon absorption and acceptor-valence band transitions. A sulphur re­lated local vibrational modes and several bands related to the optical transi­tions from the ground state of the acceptor level are observed. A comparison of transport and optical measurements for GaSb:Te and AlGaSb:Te shows that in the alloy it is easier to obtain high concentrations of the electrically active Te impurity.
