Action spectra for delayed light production by several algae were determined from 250 to 750 mmicro incident light. In the visible portion of the spectrum the action spectra resemble those reported by previous workers for photosynthesis and light emission. Blue-green algae had a maximum at 620 mmicro, red algae at 550 mmicro, whereas green and brown algae have action spectra corresponding to chlorophyll and carotenoid absorption. In the ultraviolet portion of the spectrum delayed light is emitted by algae down to 250 mmicro incident light. The action spectra of the different algae are not alike in the ultraviolet portion of the spectrum. This indicates that pigments other than chlorophyll must be sensitizing or shielding the algae in the ultraviolet region.
通过250至750毫微米的入射光测定了几种藻类延迟发光的作用光谱。在光谱的可见光部分，作用光谱与先前研究人员报道的光合作用和发光的光谱相似。蓝藻在620毫微米处有最大值，红藻在550毫微米处有最大值，而绿藻和褐藻的作用光谱与叶绿素和类胡萝卜素的吸收相对应。在光谱的紫外部分，藻类能发射延迟光，直至250毫微米的入射光。不同藻类的作用光谱在光谱的紫外部分并不相同。这表明在紫外区域，除叶绿素外的其他色素必定在使藻类敏感或起到屏蔽作用。
