Abstract
Photovoltaic cell and wavelength-shifting device, comprising a dihydropyridine condensation product chelated to a lanthanide metal ion, to expand the solar spectrum available to the cell for conversion into electricity. Method to detect an amine or an aldehyde for forming a dihydropyridine condensation product chelated to a lanthanide metal ion and measuring the long life fluorescence of the chelated metal ion to determine the amount of amine or aldehyde present.
