Yoshikawa Lab
Machine-translated · View original
The lab grows new functional crystals, such as crystals that convert radiation into light.
AboutAbout the lab
Making crystals that support safety and security.
The Yoshikawa Lab researches new crystalline materials for high-performance devices that support the safety and security of civil society.
Centered on scintillators used in nuclear medicine equipment, security inspection, and resource exploration, the lab covers everything from crystal development through evaluation to device fabrication.
It searches for unknown substances among inorganic compounds that combine many elements, and also pursues new synthesis methods.
The lab conducts many joint research projects with universities, research institutes, and companies in Japan and abroad, and members have opportunities for overseas training.
Key terms
- Scintillator
- A material that converts invisible radiation such as X-rays and gamma rays into ultraviolet to visible light
- Bulk crystal
- A crystal grown as a large block, rather than as a thin film or powder. It must be large enough to absorb radiation sufficiently
- Magnetostrictive material
- A material that expands or contracts when a magnetic field is applied, and conversely changes its magnetic state when force is applied

ResearchResearch themes
The lab seeks to understand how externally applied energy interacts with crystals, and uses this understanding to create new crystals and bring out their functions. It aims to produce world-first crystals and crystal-growth technologies and to see them put to use as devices.
*Illustrative imageScintillators
Scintillators are materials that convert radiation into ultraviolet to visible light. The lab works along three paths: searching for new materials, improving the properties of existing materials, and developing technology to produce transparent bulk crystals.
*Illustrative imagePiezoelectric crystals
Piezoelectric crystals generate electricity when strained and deform when voltage is applied. The lab's work ranges from searching for langasite-type single crystals for elastic wave devices, through evaluation with ultrasonic microscopy, to device design and fabrication.
*Illustrative imageThermoelectric materials
These are materials that directly convert heat discarded by automobiles, thermal power plants, and the like into electricity. Using nanoscale eutectic structures, the lab develops materials that suppress only heat conduction while maintaining electrical conductivity.
*Illustrative imageMagnetostrictive materials
These materials are expected to be used in devices that generate power from ambient vibration, and applications to wireless sensors that need neither batteries nor wiring are envisioned. Using the micro-pulling-down method, the lab controls the composition and shape of iron-gallium alloys at the same time, and is also searching for new magnetostrictive materials that surpass them.
