Abstract
|
|
|
|
A rapid and simple method for detecting colors was attempted on the basis of absorption and emission spectra of reflected light at 45° 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.
