AFM images of hybrid films (1 μm × 1 μm) with 50 wt% SnS
. (A) phase image of referenced MDMO-PPV film, (B) phase image of hybrid film with as-synthesized SnS2 particles, (C) phase image of hybrid film containing pyridine treated SnS2 particles, and (D) phase image of MDMO-PPV:pyridine-SnS2 film after annealing. (a)-(d) are the corresponding heitht images of (A)-(D). The scale bar in the height image indicates 40 nm.
