| 摘 要： | 通过二波耦合实验研究了C60掺杂向列相液晶中光栅形成的响应特性与光栅常数的关系。实验发现，在光栅常数较小时，光致电荷在扩散和漂移机制作用下能够很快移动到暗区形成空间电荷场，相位光栅响应较快；当光栅常数较大时，光致电较慢。荷移动到暗区时需要更长的时间，相位光栅的响应较慢。

| Abstract: | This paper introduces the influence of grating constant on response characteristics in C60-doped nematic liquid crystals(5CB) by two beam-coupling experiment. In case of the smaller grating constant, the photogenerated charges tend to more easily move to the dark zones by diffusion and drift, and are trapped by defects so that a spaced-charge field can be established within the faster response time. Compared with the large grating constant, the response time operates more slowly than the smaller grating constant. |
