Research Abstract |
We studied the fundamental optical properties of semiconductor nanoparticles with heterointerfaces and nanoparticle-based heterostructures using advanced laser spectroscopy. We clarified the magneto-optical properties of diluted magnetic semiconductor nanoparticles doped with transition-metal ions, photoluminescence properties of aligned nanoparticles and nanoparticles on different surrounding environments, and carrier recombination dynamics in nanoparticles with heterointerfaces. Novel optical functionalities were explored based on the understanding of the energy transfer mechanism at the nanoparticle interfaces.
