Table 1. Molar Ratios for NPs of Different Size^a.

NP size	Fe(CO)5/OA (molar ratio)	heating rates [K/min]
Small (3–4 nm)	1:1.7	3, 9
Medium (5–6 nm)	1:1.9	3
Large (9–10 nm)	1:3.0	1, 3, 9

^aExperimental details for the NP synthesis experiments where the size was varied by Fe(CO)₅/OA ratio and uniformity by heating rate.
