| Research Abstract |
The precipitation morphologies and induced optical functions were evaluated for transparent glass-ceramic materials with a functional crystalline phase, fresnoite, and the parameters for both material and process have been optimized in terms of the efficiency of the optical functions. According to TEM observations, the transparent glass-ceramics with highly oriented fresnoite were consist of crystallites with sizes of 20-50 nm, and they primarily form highly oriented domains with various sizes> 200 nm, which would closely related to the novel crystallization mechanism for the crystal orientation together with the transparency in a bulk form.
