Abstract
Fluorescence quantum efficiencies in solid and liquid materials were determined by simultaneous photoacoustic and luminescence experiments after excitation at several wavelengths, with at least one of them connecting a relaxation of known quantum efficiency. Results for Eu2+ in alkaline halide, Cr3+ in LiNbO3, and a cyanine in ethanol solutions, are given.
