  Among the host materials luminescence the luminescence of the self-trapped
exciton (STE) is reviewed. This luminescence, which band is situated at 2.6 to
2.7 eV, could be observed mainly under ionising radiation with energetic yield
about 0.2. The STE does not participate in pure recombination processes. Host
material defect luminescence at 5 eV appears in alpha-quartz after heavy
irradiation. It is constituted of permanent defect after neutron irradiation
and transient defect after dens electron beam irradiation. This luminescence
could be observed well at temperatures below 60 K. All another luminescence are
of impurity nature. The Ge impurity luminescence in alpha-quartz explained as
STE near Ge. The aluminium and alkali complexes. One of them is with UV band at
6 eV, appears at low temperatures and could be excited only in tunnelling
recombination process between pairs (AlO4 Me), where Me is an alkali ion
captured an electron and a hole remains on aluminium tetrahedron. Another
luminescence with band at 3.4 eV is also luminescence of complexes (AlO4 Me),
which behaviour is similar to the luminescence of alkali alumosilicate glass.
The third luminescence with band at 3 eV could be observed mainly in natural
alpha-quartz, bright at temperatures below 200 K and is interpreted as STE like
luminescence at alumosilicate clasters. The exchange of alkali ions to noble
ions of copper of silver reduces original luminescence of alumo alkali
complexes and luminescence of noble ions appears. The main band of copper
related luminescence is at 3.4 eV and that of silver is at 4.75 eV, both could
be observed up to 500 K. their nature could be well described in terms of
intraions transition. Exchange of noble ions back to alkali ions renews initial
luminescence of the samples.
