Abstract
Homogeneous transparent optical glass–ceramics precipitated with unique nonlinear crystals are promising materials for photonic applications. We have utilized heat treatment method to prepare transparent ZnO–Bi 2 O 3 –B 2 O 3 glass–ceramic containing Bi 2 ZnB 2 O 7 nonlinear nanocrystals. A large third-order nonlinear susceptibility χ (3) of glass–ceramic is measured by Z-scan technique, which mainly attributed to unique [BiO 6 ] and [B 2 O 5 ] units in Bi 2 ZnB 2 O 7 crystal structure and the quantum size effect of nanoparticles. The discovery is of great potential in the application of nonlinear optical integrated devices.
