Abstract
The absolute quantum efficiency of the fluorescence of europium thenoyltrifluoroacetonate in acetone has been measured by a calorimetric method, and substantiated by comparing the output against that from acridone. The quantum efficiency of the fluorescence, which peaks at 6122 Å, from acetone solutions at 25°C is 0.56±0.08.Keywords
