Abstract

A rapid and simple method for detecting colors was attempted on the basis of absorption and emission spectra of reflected light at $45^{\circ}$ angle from color-adsorbed filter paper illuminated by ultraviolet light through interference filter. Absorption spectra of prepared samples revealed more characteristic patterns than emission spectra. Detection of colors was readily accomplished by the investigation of wave length range, distribution pattern, the number of absorption bands and the degree of quenching.

색소(色素)를 흡착(吸着)시킨 여지(濾紙)를 시료(試料)로 간섭(干涉)필터를 통한 자다선(紫多線)을 조사(照射)한 경우에 $45^{\circ}$ 반사각(反射角)에서 발광(發光) 및 소광(消光)의 세기를 측정하여 신속하고 간편하게 색소(色素)를 감별(鑑別)할 수 있는 방법(方法)을 시도(試圖)하였다. 발광(發光) 스펙트럼 보다는 흡수(吸收) 스펙트럼이 보다 특징적인 패턴을 나타냈다. 흡수대(吸收帶)의 파장영역(波長領域), 분포상태(分布狀態) 및 개수(個數)와 소광(消光)정도를 조사하므로써 착색료(着色料) 종류가 용이하게 판별되었다.
