Description:

Many of the observed superior optical, magnetic, and electronic properties of composite materials are the result of collective behaviors of the nanocrystalline phases in amorphous systems, which do not exist for any of the neat phases alone. Research works to determine the underpinning mechanisms governing metal cations in amorphous systems and explore a novel methodology that can be applied to precision fabrication of nanophase glass ceramics with designed chemistry and structures at a nanoscale.

This research shows that metal cation clustering in glass can be utilized to control nano-/micro-phase formation and crystal morphology, such as the hollow microcrystals of rare earth silicate shown here.  Precision fabrication of superior nanophase glass ceramic materials with controlled design of chemistry and structures will help develop materials that can be used for optical communication, data storage, etc.
