GSN
Crystals of GSN were grown by a slow evaporation technique published by the authors elsewhere [1]. A crystal was then selected and observed by scanning electron microscopy (SEM) in order to analyze the morphologic and surface characteristics. Fig. 1 shows the image obtained by SEM of a GSN nano-monocrystal using a JEOL JSM-5800LV microscope, with an acceleration voltage of 15 kV and a current of 40μA. A crystal with vertices and defined angles was observed, with facets with flat surfaces, which also possessed parallel facets with an elongated form. Moreover, a series of impurities were noticed, mainly white spots on the surface of the faces, which correspond to the precipitated salts that did not obtain favorable crystallization
