在光诱导相变中，晶体取向和光的偏振方向或波矢量之间的关系似乎很重要，但令人惊讶的是，光诱导相变中的这种方向性尚未得到很好的实验研究。表现出Ti和O离子各向异性迁移的结构相变，其纳米晶体表现出持续的光致相变。我们发现，即使在这种化合物的单晶中也会发生光致相变，但这在很大程度上取决于光被照射的平面的方向。这种光诱导相变的选择规则主要取决于与相变相关的应变的各向异性。
In photoinduced phase transitions, the relationship between the crystal orientation and the direction of the polarization or wave vector of light seems important, but surprisingly, such directional properties in photoinduced phase transitions have not been well studied experimentally.exhibits a structural phase transition involving the anisotropic migration of Ti and O ions, and its nanocrystals exhibit a persistent photoinduced phase transition. We found that a photoinduced phase transition occurs even in a single crystal of this compound, but it significantly depends on the orientation of the plane on which the light is irradiated. Such a selection rule for photoinduced phase transitions is dominated by the anisotropy of the strain associated with the phase transition.
