Abstract
In this work we report PL characterization of single heterostructures obtained when GaAs is grown on top of GaO.51InO.49P by LPE. Wide structured PL band in the range 1.4-1.5 eV is characteristic for these structures. The obtained results reveal that this band can be related to the presence of arsenic vacancies in the GaAs layer adjacent to interface. The component with peak at 1.454 eV in this band we ascribe to recombination within a complex (VAs - group IV atomAS)
