A lab that experimentally explores the optical properties of nanostructures and phosphors.
AboutAbout the lab
Exploring how light is produced in the nano world.
The Quantum Optical Properties Lab experimentally studies the optical properties of new phosphor materials, nano-optical materials, and semiconductor microstructures.
The lab works to clarify the optical properties of quantum confinement structures such as quantum dots and nanowires, and their interactions with luminescent centers.
It searches for new materials and phenomena that contribute to low energy consumption and are environmentally friendly.
On the lab's website, it is introduced under the name "Quantum Optical Properties Lab."
Key terms
- Quantum confinement structure
- A structure in which electrons are confined in a small nanometer-scale region. Wave-like properties become prominent, changing the color of emitted light and the response speed.
- Quantum dot
- A type of zero-dimensional quantum confinement structure. Its optical properties are studied along with those of nanowires and other structures.
- Luminescent ion
- An ion that serves as the source of light emission. When introduced into a nanostructure, it can make the material emit light with an intensity or color different from the usual.
ResearchResearch themes
In semiconductor microstructures with sizes in the nanometer range, the wave-like nature of electrons becomes prominent, which may make it possible to freely control the color of emitted light and the response speed. The lab creates new nano-optical materials by introducing luminescent ions into such structures, and aims to elucidate their structures and light-emission mechanisms.
