Abstract: Abstract:Structural and luminescence properties of GaSe1−x S x (0 ≤ x ≤ 1) series optical materials have been studied by X-ray diffraction, photoluminescence (PL), and piezoreflectance (PzR) measurements. Powder X-ray diffraction patterns showed the whole series layers present three different kinds of stacking formula with respect to the compositional change of sulfur from x = 0 to x = 1. The comparison of PL and PzR spectra reveals that the GaSe1−x S x layers have three different kinds of stacking phase from x = 0 to x = 1. The PL results show the whole series GaSe1−x S x layers emit the luminescences from red to blue visible region. The PL and PzR spectra of the GaSe1−x S x are analyzed. The structural variation in between the layers is discussed.
