γ‐Fe 2 O 3 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 ( γ ‐Fe 2 O 3 –CdSe) nanocomposites are also synthesized in high yield, with a photoluminescence quantum yield of up to 42%.
