Emission characteristics upon a intense excitation in conducting polymers such as poly (p-phenylenevinylene) derivatives have been studied. Spectral narrowing of photoluminescence has been observed above a threshold intensity of photoexcitation, which is recognized in a solution of the conducting polymers as well as a film. Even in polyacetylene derivatives which have been considered as nonluminescent polymer, intense photoluminescence and its spectral narrowing have been observed. Spectal narrowing and laser action in conducting polymer infiltrated synthetic opal which has periodic structure of light wavelength range, have also been investigated. A fine structure has been observed in the photoluminescence spectrum of polymer-infiltrated opal. The wavelength of the sharp peak depends on the diameter of SiC_2, spheres and refractive index of the solvent, which is associated with laser action originated from the optical feedback due to the periodical structure of opal.

研究了导电聚合物如聚对苯撑乙烯衍生物在强激发下的发射特性。已经观察到光致发光的光谱变窄在光激发的阈值强度以上，这在导电聚合物的溶液以及膜中被识别。即使在聚乙炔衍生物，一直被认为是非发光聚合物，强烈的光致发光和光谱窄化已被观察到。研究了具有光波段周期性结构的导电聚合物渗透合成蛋白石的光谱窄化和激光作用。在聚合物渗透蛋白石的光致发光光谱中观察到了精细结构。锐峰的波长与SiC_2的直径、球的大小和溶剂的折射率有关，这与蛋白石的周期性结构引起的光反馈作用有关。
