## Title

- title: Recent Progress in Controlled Nanostructure of Colloidal Nanocrystal Powders
    for Efficient Light Emission
  title_type: original

## Description

- description: The application of semiconductor nanocrystals containing cadmium, lead,
    selenium and mercury as constituent elements is strictly limited by concerns about
    environmental pollution and health effects. Nanocrystals free of these toxic elements
    are being pushed to the forefront of nanocrystal 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 of these environmentally friendly fluorescent nanocrystals.
    In this context, the first topic in this review 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 such as tin-based halide perovskite
    and double perovskite structures. Recent efforts on how to control nanostructures
    to enhance photoluminescence quantum yields is highlighted for each semiconductor
    nanocrystal.
