A glass of 47.5BaO · 47.5B2O3 · 5Al2O3 (in mol%) having a shorter optical absorption edge (∼236 nm) and suitable glass formation was selected as the mother glass for studying the surface crystallization of β−BaB2O4 · β−BaB2O4 was not the main surface crystallized phase when only a conventional heat treatment was applied. Crystallization of β−BaB2O4 was stimulated due to ultrasonic surface treatment with an ethanol suspension of β−BaB2O4 particles and subsequent heat treatment. After the ultrasonic treatment, β−BaB2O4 was the main crystallized phase. Transparent and dense β−BaB2O4 thin films/glass showed second harmonic generation. The tensor components of the second-order nonlinear optical susceptibility were estimated.

Glass-ceramics containing ferroelectric CsLiB6O10 crystals were prepared by heat treating Cs2O–Li2O–B2O3 glasses. Second harmonic generation (SHG) was observed from samples prepared by two-step heat treatment (nucleation and growth); however, the intensity was rather weak. On the other hand, one-step heat treatment by the addition of a small amount of TiO2 to the glass resulted in the glass-ceramics containing small single crystal-like CsLiB6O10 particles. The strongest SHG observed was comparable with that of Y-cut quartz. The preferred orientation of precipitated CsLiB6O10 crystals was attributed to the occurrence of SHG from the glass-ceramics.

CdS doped lead silicate glasses were prepared with the conventional fusion method. The effects of the ZnO/CdS ratio and the content of CdS on the preparation of CdS doped glasses were both studied. The crystallization process of CdS nanocrystals was investigated by X-ray diffractometry and scanning electron microscopy. Utilizing the Maker fringe method, Second harmonic generation (SHG) was observed from CdS doped glasses without any poling procedures. The SH intensity gets enhanced by increasing the heat-treatment temperature and prolonging the heat-treatment duration.
