Abstract
Fluorescent brightening agents are widely used in various
industries to enhance the appearance of materials. In
order to describe the colour of a fluorescent surface,
accurate measurements of fluorescence emission are
needed. In this work, measurements of goniometrically
resolved bispectral luminescent radiance factors are
presented with improved uncertainties. In addition, a
method for goniometrically determining the spectral
quantum efficiencies of the fluorescent process is
presented and validated. The advantage of goniometric
measurements is that they avoid the need to assume a
specific angular emission profile of the fluorescent
sample.
