Structural and optical properties of two- and three-layer epitaxial heterostructures containing GaInP/Ga{sub x}In{sub 1-x}As{sub y}P{sub 1-y} quaternary alloy layers were studied. Domain formation due to spinodal decomposition of the quaternary alloy was detected in three-layer heterostructures. As a result, an additional long-wavelength band appears in the photoluminescence spectra, and an additional doublet of the CuK{sub {alpha}}{sub 1,2} line appears in X-ray diffraction patterns of the (006) line. The domain composition was determined on the basis of Vegard's law and the Kouphal equation.
