Silicon carbide (SiC) quantum dots (QDs) are eminent candidates for various exciting applications ranging from bioimaging and energy conversion, to optics. In this talk, we describe a new top-down method for producing SiC QDs ( 50 nm) and slurries. Photo-assisted electrochemical etching is employed to obtain the quantum-sized clusters. We show that the process (hence, the amount of QDs synthesized as well as their size) can be controlled via regulating time and temperature as confirmed by both high-resolution transmission electron microscopy and photoluminescence studies. The presented method may serve as a new avenue to prepare size-controlled nanoparticles of different semiconductor materials.
