Measurement of the Color Characteristics and Brightness of Fluorescent and Phosphorescent Material
Abstract
The physical basis of color measurement is discussed; and an experiment comparison is made of the photoelectric and spectrophotographic method for determining the spectral distribution of energy from fluorescent and phosphorescent material. An R. C. A. photomultiplier tube with a D. C. amplifier is used as a detecting instrument. Samples of fluorescent cloth radiating in the visible portion of the spectrum when excited by light from a G. E. S.-4 high intensity mercury arc, were examined and color characteristics measured. It was concluded that the photoelectric method was simpler, more rapid and accurate than spectrophotographic methods.
