Abstract

Excitons in Cu2O have been studied extensively since their discovery nearly 30 years ago.1 Excitons of the fundamental(yellow) series are both very sharp and difficult to observe as a result of the direct forbidden bandgap. Yellow P states are weakly dipole allowed, and 8 or more members of the P series can be observed in good crystals in absorption or luminescence. Yellow S states, however, are strictly dipole-forbidden.
