From the paper: For the wavelength-dependent evaporation measurement, we used LED with different wavelengths. LED lamps were purchased from Chanzon with rated power of 100 W and different wavelengths: purple 390nm, blue 440nm, green 520nm, yellow 590nm, red 650nm, and IR 850nm. Note that rated power is not the same as energy. E=hf. Since green had the most impact on evaporation, this phenomenon is not similar to the photoelectric effect.
