Overall quantum yields of the homogeneous photoreactive system at different catalyst (Ccat) and Eosin Y (C) concentrations in mol.m−3.

Results obtained from Eq 63, using several methods to estimate : φ(exp,0) uses measurements on ballistic radiation (fluorescence is neglected), φ uses the reference Monte Carlo calculation, φ(Φ=0) uses model results when fluorescence is neglected, uses the gray single-scattering analytical approximation presented in Section 4.3. Relative error δ with respect to the reference value φ is provided (see Eq 66). Optical thicknesses and are calculated from Eqs 4 and 6, with for the LED emission spectrum.
