摘要：
FeS2 nanoparticles were prepared by microwave method using tri-sodium citrate and sodium tartrate as complexing agents to study their effect on the optical properties and stability for 21 days without special storage conditions. FeS2 nanoparticles showed absorption in the visible range with a single-phase of cubic pyrite and crystallite size around 17.5 +/- 2.92 nm. Moreover, nanoparticles showed a low photoluminescence intensity. The FT-IR spectra indicate the presence of chemical bonds around the nanoparticles. FE-SEM images showed spherical shape and size distribution in the range of 15-30 nm depending on the complexing agent. The use of complexing agents modifies the size and shape of FeS2 nanoparticles influencing the tuning of absorption and emission spectra through a period of time.
