Laser Figure shows the microstructure, crystal phase and oxidation state of the synthesized SnO nanoflowers. Fig. demonstrates the expected interlocked disc nanoflower structure for particles produced in IPA . The flower morphology comprises intersecting micron-scale disks with diameters of 4.0 ± 0.5 m and thickness ≈ 400 nm (see Fig. ). SnO forms through a dissolution-reprecipitation process of intermediated Sn6O4OH4 to produce nanoscale plates that aggregate into larger structures . A1g/Eg peak area ratios correspond inversely with number of layers of SnO . We found A1g/Eg peak area ratios ranging from 1. 10-layers, which matches well with the large nanoflower particle structures. Assuming a Lorentzian Peak shape and applying the Scherrer formula for the (101) peak we find crystallite size of ≈ 1.08 nm in the direction perpendicular to the plane. This deviates from the observed particle thickness which is on the order of 100 nm and corresponds with a mesoscale structure composed of numerous aligned nanoparticle building blocks as observed for SnO in the literature .
