Iron based chalcogenides nanocrystrals (NCs) hold considerable promise for both solar energy conversion and electrical storage. Their utilization is hampered by lack of control over crystallinity and nanoscale organization of the homogeneous fabrications, the availability of high quality NCs of these materials will help us understand better both the photophysical processes in them and acquire building blocks to make better mesoscale materials from them. Therefore, two kinds of ~30nm diameter NCs FeSex (X=1, 2) have been synthesized and which display strong photoluminescence indicative of minimal defect density which are previously unavailable. FeSex (X=1, 2) displays photoluminescence (PL) peaks at 447nm and 462nm respectively while quantum yields are as high as 20%. Additionally, the synthetic route for iron based ternary chalcogenides NCs also have also been developed by doping Cr elements in the synthetic process, i.e., FeCr2Se4 and FeCr2S4 are synthesized through using a facile wet chemical method. FeCr2Se4 and FeCr2S4 NCs possessed narrow size distribution with high quality. FeCr2Se4 and FeCr2S4 NCs offer a promising conductivity for integration as electrical application. Importantly, these colloidal NCs can be considered be suitable for biomedical fluorescence marker and as the environmentally benign substitutes for optical, electronic and photovoltaic materials. Additionally, iron based bimetallic magnetic nanomaterials have been studied as advancement.
