PHOTOCHROMIC MATERIAL AND COLOR DOSE METER USING THE SAME

摘要

A photochromic material which comprises an illuminant emitting a light by the irradiation of a radiation thereto and a diarylethene type photochromic compound having a specific structure; and a color dose meter using the photochromic material. The dose meter can be used for detecting a radiation irradiated with good efficiency and determining the dose of the radiation with improved sensitivity.
