Absolute measurements of photoluminescence quantum yields of solutions using an integrating sphere.

Porres, L. and Holland, A. and Palsson, L.-O. and Monkman, A. P. and Kemp, C. and Beeby, A. (2006) 'Absolute measurements of photoluminescence quantum yields of solutions using an integrating sphere.', Journal of fluorescence., 16 (2). pp. 267-273.

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.
