THE ANOMALOUS VIOLET-SHIFT OF ABSORPTION EDGE OF LiNbO3 CRYSTALS OF THE SOLID-LIQUID CONGRUENT POINT COMPOSITION
固液同成分点组分的LiNbO3晶体吸收边的异常紫移

The experimental result of anomalous violet-shift of absorption edge of LiNbO3 crystal of the solidliquid congruent point composition is presented. This resultis conducing for showing that the existence of the solid-liquid congruent point corresponds to the strongest Nb-0 bonding state.
