“…The peaks at 2θ values of 22, 26, 27.5, 30.5, 31.5, 31.7, 32, 39.1, 44.8, 45.5, 48.5, 48.6, and 56.7° correspond to the (101), (201), (210), (011), (111), (301), (400), (311), (020), (220), (302), and (420) planes of SnS (PDF# 73-1859). The strong XRD peaks refer to cubic ZnS and orthorhombic SnS structures representing better crystallinity and grain formation. − …”
