Upconversion nanoparticles with the excitation in the NIR range and the emission in the visible range, which have overlap with the absorbance of the lycopene have been used for the lycopene detection. Thus caused colour change in the upconversion paper is proportional to the lycopene concentration, which is precisely quantified with the phone camera.
