IONCs with an edge length of 16 ± 2 nm were prepared
according to previously reported protocol.19 (link),35 (link) Briefly, 1 mmol (0.353 g) of iron(III) acetyl acetonate, 4 mmol
(0.69 g) of decanoic acid, 7 mL squalene, and 18 mL of dibenzyl ether
were dissolved in a 100 mL three-neck flask. After degassing for 120
min at 65 °C, the mixture was heated up to 200 °C at a rate
of 3 °C/min, and this was maintained for 2.5 h. Later, the reaction
temperature was raised to 310 °C (at a rate of 7° C/min),
and the reaction continued for 1 more hour. Next, the solution was
cooled down to room temperature, and 60 mL of acetone was added and
centrifuged at a rate of 4500 rpm. After two washes, the dark pellet
was redispersed in 15 mL of chloroform.
