Development of Novel Scintillator and Piezoelectric Crystals



Our research target is mainly focused on the topic of development of novel scintillator crystals, piezoelectric crystals, growth technology, characterization and its device application.
We design and synthesize new materials from a view point of Crystal Chemistry, and investigate their structure and physical properties. We also study on photo-detector, as suitable photo-detector fully contribute to get maximum signal from scintillator. This activity is very important to realize practical application of our developed materials. Recently, piezoelectric material and high melting temperature alloy project is also started.

Targeted Application(s)/Industry

For the purpose of "real" contribution to human culture, we are always carrying out our research activity considering the industrial application. This point is unique feature of our attitude toward science.
