Fig. 9From: Burst nucleation by hot injection for size controlled synthesis of ε-cobalt nanoparticlesTEM images of ε-Co NPs synthesized at \(\frac{[Co]}{[OA]} = 6.5\). Samples are synthesized at a 441 and b 446 K, injection time = 5 s, reaction holding time = 1800 s. Their corresponding particle diameter distributions are obtained from counting ~300 particles.
