Generation of photofluorescent materials by short wavelength ultraviolet irradiation of non-fluorescent bis-diarylchloromethyl-1,3,4-oxadiazoles

摘要

A system for the transcription of expressions comprising a member incorporating a non-luminescent material transformable to a photoluminescent material by transcriptive light-activation of short-wavelength which resultant fluorescent transcription is made discoverable by light-activation of longer wavelength.
