Fluochronometer for measuring fluorescence decay times of the nanosecond order
Abstract
A statistical photoelectron method is used to explain the principle behind measuring the nanosecond decay times of weak fluorescence. A fluochronometer is described, with emphasis on the characteristics of the exciting pulsed light source, and the photomultiplier tube for fast fluorescence detection. The device is applied to the study of the fluorescence lifetimes of macromolecular photosynthetic systems at temperatures between 23 deg and 276 deg K.
