Abstract It is shown that two differently oriented (perpendicular and parallel to the c axis) serf-trapped excitons (STE ⊥ and STE ∥ ) can be created in the range of the Urbach tail of the fundamental absorption of α-quartz. Below this tail no STE luminescence was found. The alkali ion centers, excited below the tail, give luminescence bands, which can be replaced by substituting alkali ions with Cu + ions. It is concluded that both STE ∥ and STE ⊥ are intrinsic.
