Abstract: Multi-modal artifact metrics is an anti-counterfeiting technique, and was created based on the concept of multimodal biometrics. By this method, additives (functional materials) are added to the artifact during the manufacturing process in order to provide multiple feature information. Hence, the certainty of authenticity and difficulty of counterfeiting could be enhanced. In order to provide two kinds of optical characteristic information (emission intensity and hue) into the artifact, we developed a new type of glass phosphor. This is a novel approach, since up-conversion phosphors with different hue and emission intensity by optical excitation at each observation point have never been reported. In this paper, we report the development of this glass phosphor, especially the production method and results of the fundamental experiments. The developed glass phosphor emitted as intended and demonstrated the validity of our approach.
