説明

The alkali borosilicate glasses containing CdS as a constituent were heat-treated or thermally poled to prepare CdS microcrystal-containing glasses. Second harmonic generation (SHG) from these glasses was measured, and the effects of the applied voltage on the crystallization behavior and SHG intensity were discussed. In poled glass samples, wurtzite type CdS microcrystals were precipitated at lower temperature than in unpoled ones. It was considered that the applied electric field affected the crystallization behavior of CdS crystals through the increase of temperature of the glass sample and migration of S2− ions. The poled sample showed larger SHG intensity than the sample merely heat-treated, which was explained in terms of modification structure and orientation of precipitated CdS microcrystals.
