The theory of exciton spectrum in multi-shell hexagonal semiconductornanotube is developed within the effective masses and rectangular potentialsapproximations using the method of effective potential. It is shown that theexciton binding energy for all states non-monotonously depends on the innerwire diameter, approaching several minimal and maximal magnitudes. The obtainedtheoretical results explain well the experimental positions of luminescencepeaks for GaAs/Al_{0.4}Ga_{0.6}As nanotubes.
