Figure 1. SEM recorded with back-scattered electrons of alloy NPs.

Figure 1

The images depict Au0.5Pt0.5 alloy NPs with different particle sizes [(a) 6 nm, (b) 10 nm] and interparticle distance [(a) 20 nm, (b) 70 nm] as produced using two different block copolymers [(a) PS(227)-b-P2VP(99) and (b) PS(1056)-b-P2VP(495)]. The concentration of the micellar solutions was identical: c = 3 mg/ml, loading L = 0.4.
