Dr. Yoshiki Yamazaki of graduate student in Department of Applied Physics, Graduate School of Engineering, Tohoku University, (currently, outside researcher of National Institute of Advanced Industrial Science and Technology), Assist. Prof. Yoshihiro Takahashi and Prof. Takumi Fujiwara have succeeded in fabricating a highly-transparent glass-ceramics, in which many nano-sized amorphous particles are parasitic on the single-crystal domains, on a level with optical-grade material. Although single-crystal material has been dominated in the field of photonic materials, this development is expected to contribute to creation of photoceramics with specific polarization/orientation and refractive index structures, and its application to optical device.

 The results of this research were published online in the British natural science journal "Scientific Reports" on January 28. The paper's title is "Parasitic amorphous on single-domain crystal: Structural observations of silicate glass-ceramics."
