摘要：Maghemite (γ-FeO) is formed by oxidizing iron stearate with methylmorpholineN-oxide (MNO). A mixture comprising iron stearate, MNO, a surfactant, and a solvent maybe heated to maintain the mixture at a temperature of about 280 to about 320° C. for asufficient period to form magnetic nanoparticles comprise maghemite. After heating, themixture may be cooled to limit growth in size of the nanoparticles. The mixture may beheated for a period of about 15 minutes to about 30 minutes, such as about 15 minutes.The process may be adapted to also form quantum dots, and to form magnetic quantumdot (MQD) nanoparticles in an integrated process.
