室温下波长为1.06μm 的红外激光照射高等植物叶片,获得在可见区内的荧光发射谱,它们来源于叶片中类胡萝卜素的多步多光子跃迁所诱导的荧光,为植物光合作用研究提供了用信息,并报道了探洲生物样品荧光的简便有效方法。 At room temperature, the infrared laser with the wavelength of 1.06μm irradiates the leaves of higher plants to obtain the fluorescence emission spectrum in the visible region, which is derived from the fluorescence induced by the multi-step multiphoton transition of carotenoids in the leaves, which provides the study of plant photosynthesis With the information, and reported the fluorescence of biological samples explore a simple and effective method.
