a Smoothed fluorescence spectrum of a G1000 microsphere immersed in water with the black line indicating the polynomial used for background subtraction. b Image of a microsphere in water with spores adsorbed. The image is slightly defocused in order to see both the microsphere and spores. c Processed experimental spectrum (red) superposed to the best fit of calculated EMT spectrum (black) displaying the near perfect agreement between theory and experiment
