“…The XRD pattern depicts the reflections of (111), (200), (220), (311), and (400) peaks at 2θ angles of 25.36°, 29.71°, 41.88°, 49.86°, and 60.97°, respectively, indicating the presence of a major zinc blende (ZB) structure in alloy NPLs (Figure a) . The reflection for alloy NPLs shifts toward the higher angle, compared to the CdSe NPLs after incorporation of S 2– ion in place of Se 2– ion in alloy NPLs . The morphology of the 2D 4-ML CdSeS alloy NPLs is investigated using transmission electron microscopy (TEM).…”
