UV LEDs using ZnO nanoparticles
World’s first UV LEDs using nitrogen doped ZnO nanoparticle coatedfilms have been developed. Low cost solid state lighting devices will
be realized without single crystal substrates and epitaxial growthtechniques, because this LEDs only use nanoparticle films on glassor metal substrates.

Growth of ZnO films using MOCVD
We have developed MOCVD (Metalorganic
Chemical Vapor Deposition) system with ahigh-speed rotating disk. We are trying todevelop high quality ZnO films using MOCVD.

We design new dielectric materials to understand physics better. In turn, we are curious how the dielectric properties
can be controlled by temperature and electric field. We take multidisciplinary approaches integrating various sample
preparation technique and measurements to solve pressing problems in physics as well as engineering.

Our study: We study on a technique to visualize the behavior of molecules functioning in living cells by
Raman spectroscopy. Raman spectroscopy is a technique which let us know the structures andconditions of molecules by analyzing the vibrations of molecules. The technique has been recently more
widely used in the frontier of clinical applications.
An example of our study: We have found a fission yeast mutant strain, which cannot grow well due tothe lack of coenzymeQ10 (CoQ10, a coenzyme essential for respiration) synthesis, grows fairly by theaddition of CoQ10 inclusion complex (Figure 1). By Raman mapping and other studies, we have foundthat the recovery in the growth was not brought about by the recovery of respiration activity but by theanti-oxidative function of CoQ10 (Figure 2). We await for your interest in our study!!

Objective: Our group is working on medical and biologicalapplications of Raman spectroscopy.
Raman spectroscopy is a technique to give us structuraland environmental information on molecules by theirvibrational spectra, which are frequently called as“molecular fingerprints”.
We utilize this technique to elucidate, e.f. the metabolic
activity of living cells, diagnosis of various diseases.
