“…The pulsed and continuous-wave CO 2 laser induced homogeneous decomposition of selenophene and tellurophene in the presence of SF 6 sensitizer [ 55 ] is controlled by cleavage of both X-C (X=Se, Te) bonds and yields elemental chalcogen along with 1-buten-3-yne, ethyne, ethene and buta-1,3-diene (major products, selenophene) and 1-buten-3-yne (major product, tellurophene). The higher SF 6 content in the irradiated selenophene-SF 6 system increases the mean effective temperature and leads to higher relative amounts of ethyne and lower amounts of 1-buten-3-yne and ethene.…”

Laser radiation-induced decomposition of gaseous organic selenides and tellurides resulting in chemical deposition of nanostructured materials on cold surfaces is reviewed with regard to the mechanism of the gas-phase decomposition and properties of the deposited materials. The laser photolysis and laser thermolysis of the Se and Te precursors leading to chalcogen deposition can also serve as a useful approach to nanostructured chalcogen composites and IVA group (Si, Ge, Sn) element chalcogenides provided that it is carried out simultaneously with laser photolysis or thermolysis of polymer and IVA group element precursor.
