Effect of Temperature on Fluorescence Quantum Yields in Solution

Abstract

Fluorescence quantum yields and lifetimes have been measured as a function of temperature for anthracene and 9,10‐dichloroanthracene in hexane and ethanol. It was found that the radiative transition probabilities are very slightly temperature dependent. However, for the nonradiative processes, 9,10‐dichloroanthracene shows a strong temperature dependence, whereas anthracene shows none.
