碩士 === 南台科技大學 === 機械工程系 === 101 === In the study, we use Thermo decomposition to preparation for this transition metal-substituted iron-sulfide nanoparticle, Another study was replaced by cube pyrite, by different concentration of reactants Observations Fe1-xCrxS and Fe1-xCoxS2 change, The concentration of reactants ratio would peak the entire left shift Found in the X-ray changes. We use XRD patterns of the synthesized Fe1-xCrxS and Fe1-xCoxS2 nanocrystals with various mean crystallite sizes, and can notice that range of size is were the 9 nm to 26 nm and 24 nm to 32 nm, whether there is mixed success. The magnetic analysis is used of SQUID,EPR and Mossbauer, find that particle of different concentration have different result. We use TEM and SEM observe the surface type state and microstructure.
