PLASTIC MOLDING AND METHOD OF PREDICTING WAVELENGTH OF IRRADIATION LIGHT

摘要

A plastic molding capable of being luminescent with prolonged emission lifetime. There is provided a plastic molding characterized in that it contains at least one luminescent compound selected from the group consisting of a Nile red luminescent compound, a coumarin luminescent compound, a quinacridone luminescent compound, a carbazole luminescent compound, an oxadiazole luminescent compound, an organic aromatic compound having aromatic rings linked through methylene with each other, a stilbene luminescent compound, a dialkylfluorene luminescent compound and a single luminescent compound capable of white light emission, and that it is capable of light emission by irradiation with light of wavelength shorter than that of the emission peak of the at least one luminescent compound, and that it is one having passed through plastic molding operation.
