Abstract

Glasses with composition (100 - x) TeO2-x LiNbO3 (10 less than or equal to x less than or equal to 50) were prepared by conventional melt-quenching. The glass-formation ability, dielectric and optical properties of these glasses were studied. LiNbO3 microcrystallites were directly precipitated on the surface of the glass, with the composition 50 TeO2 - 50 LiNbO3, by a single step heat treatment. The polar nature and second-order optical non-linearity of the transparent surface crystallized glasses are manifested in their strong pyroelectric response, ferroelectric hysteresis and intense second harmonic generation of 1064 nm wavelength radiation.
