The relative fluorescence quantum yield (η) of AIETP NPs in aqueous media was calculated using freshly prepared Rhodamine B as the standard (η = 0.7 in methanol). The η value of AIETP NPs was found to be 0.06 when calculated using the following equation:

where, A is the absorbance at the excitation wavelength, F represents the integrated fluorescence intensity, n is the refractive index of the used solvent, and the subscripts 1 and 0 signify the experimental sample and the standard respectively.
