| 中文摘要 | from the chemical bond viewpoint, second-order non-linear optical (nlo) tenser coefficients of knbo3 and linbo3 crystals have been calculated. by using the bond-valence theory of complex crystals and the modified bond-charge model, we were able to determine contributions of each type of constituent chemical bond to the total second-order nlo susceptibility. the tenser values thus calculated are in good agreement with experimental data. from the comparison of nlo tenser coefficients of these two crystals, we found that the major nlo contributors are ko12 groups and lio6 octahedra not the distorted nbo6 octahedra. the difference between their nlo properties arises from their different structural characters, and the high coordination number of constituent elements in knbo3 makes its valence electrons become more delocalised compared with those of linbo3.
