## Description

- description: Nanocrystals free of toxic elements are being pushed to the forefront
    of nanoscience research because of their environmentally friendly advantages and
    attractive photophysical properties on recent advances in colloidal synthesis,
    excellent optical properties, optoelectronic device applications, and biological
    applications. In this context, the first topic in this paper introduces group
    IV semiconductors. In particular, the unique light emitting properties generated
    in silicon nanocrystals of diameters smaller than Bulk exciton Bohr radius are
    highlighted. Next the topic turns to the nanocrystals of group III-V semiconductors.
    After that, attentions are paid to the lead-free perovskite nanocrystals with
    double perovskite structures. Recent efforts on how to control nanostructures
    to enhance photoluminescence quantum yields is highlighted for each semiconductor
    nanocrystal. Finally, the remaining challenges that must be overcome to realize
    nontoxic optoelectronic devices will be discussed.
