貝殻の焼成により観察される蛍光特性を利用したヤマトシジミの産地評価

摘要

The fluorescence samples (CaO matrix and Mn activator) was prepared by firing corbicula japonica shells at 900°C, where the origin places of those were the lake Abashiri, the lake Ogawara, the Kisogawa, the lake Ju-san, the lake Shinji and the lake Hinuma. All the samples showed orange color fluorescence with the peak at 594 nm. The fluorescence intensity increased with increase of the Mn/Ca ratio of the samples except the sample of the lake Ju-san.
