TEM and HRTEM images of the nanoparticles. Representative (a, b) TEM, HRTEM (c, d, e) of boxed areas (in a, b) images and size histogram made by counting over 100 particles from b TEM (f) of exfoliated by PANI–powdered GaSe nanoparticles. In the (c) and (d) images, the lattice planes could be attributed to the (0001) direction along the crystallographic c axis, while in the (e) image, to the (10–10) direction along the crystallographic a axis of hexagonal GaSe.
