Abstract
A spectrophosphorimeter with a single spectrometer so as to obviate the need of a couple of spectrometers of conventional spectrophosphorimeters, wherein one spectrometer is operated as an excitation-side spectrometer only when the light is allowed to pass a light interceptor, and the other spectrometer works as a phosphorescence-side spectrometer only when the light is substantially interrupted. The single spectrometer is used on the excitation side when the light is allowed to pass and on the phosphorescence side when the light is interrupted.
