Abstract:

The mono-dispersed CuFeS2 nanocrystals(NCs) with tunable sizes were synthesized and characte-rized by UV-Vis-NIR absorption spectroscopy, transmission electron microscopy(TEM), X-ray powder diffraction(XRD) and inductively coupled plasma(ICP). It is found that the as-prepared CuFeS2 NCs show photoluminescence in visible region. The photo-responsive properties of CuFeS2 NCs further reveal their suitability as optically active components for optoelectronic devices and the growth in size due to the quantum size effect. All the experimental results indicate that as-prepared CuFeS2 NCs with characteristics of fluorescence has potential application in biomedical imaging and optoelectronic devices.
