Facile Synthesis of Fe2O3 Nanocrystals without Fe(CO)5 Precursor and One-Pot Synthesis of Highly Fluorescent Fe2O3-CdSe Nanocomposites

gamma-Fe2O3 nanocrystals are synthesized in high yield (2 g) without a hazardous precursor and with a less-expensive oxidant in a one-pot synthesis (see figure). Bifunctional magnetic quantum-dot (gamma-Fe2O3-CdSe) nanocomposites are also synthesized in high yield, with a photoluminescence quantum yield of up to 42%.
