我们成功地将聚合物溶液自旋涂覆在聚酰亚胺单向摩擦的玻璃基板上，制备了单域聚合物胆甾液晶（PCLC）薄膜。通过控制自旋涂布机的转速和聚合物溶液的手性单元含量，可以很好地表征聚合物的厚度和螺旋节距。证实了利用光子结构从掺杂染料的PCLC薄膜中发出激光。
We have succeeded in fabricating monodomain polymer cholesteric liquid crystal (PCLC) films by spin coating a polymer solution onto glass substrates with polyimide coated and rubbed unidirectionally. The thickness and helical pitch were well characterized by controlling the rotational speed of the spin coater and the chiral unit content of the polymer solution, respectively. Lasing from dye-doped PCLC films utilizing the photonic structure was confirmed.
