AI Article Synopsis
- The study presents a method to measure the photoluminescence quantum yield of solutions using an integrating sphere attached to a conventional fluorimeter.
- This technique eliminates the necessity for using luminescence standards in measurements.
- Various compounds were tested, and the findings were compared with existing literature values and data from traditional comparative methods.
Article Abstract
We demonstrate that absolute measurements of the photoluminescence quantum yield of solutions can be made using an integrating sphere and a conventional fluorimeter. With this method the need for measurements against a luminescence standard is overcome. The sphere is mounted inside a commercial fluorimeter, which gives flexibility in excitation and emission wavelength ranges. A number of compounds have been investigated and the results are compared to literature values and data obtained using a comparative method.
