The fluorescence of naphthalene crystals has been observed through a phosphoroscope indicating that a part of this emission has a lifetime greater than 10—3 sec at 4.2°K. It is suggested that this phenomenon is connected with the photoconductivity observed in crystals of aromatic compounds and has its origin in the storage of energy by an electron trapping mechanism.
