Development of Functional Material for anti-Counterfeiting and Authenticity Verification of Ceramic Products

Masaki Fujikawa, Mariko Hara, Yasushi Nanai, and Shingo Fuchi
Abstract—This study introduces a functional material called glass phosphor, which emits both visible and near-infrared spectra via optical excitation using 980-nm light. This glass phosphor exhibits both up and down conversions while receiving only one excitation light. This transparent, harmless, and pale pink material has affinity with the glassy layer of a ceramic product, and the ceramic product’s patterns and colors remain unaffected when a small amount of phosphor powder is welded onto its surface. After the powder had been welded, four types of optical feature data were extracted from the ceramic product and used to verify its authenticity. Because the genuine product’s hue, emission intensity and the light path generated by the glass phosphor particles are hard to replicate, the powder of this material could be used for anti-counterfeiting of the genuine product.

Index Terms—Anti-counterfeiting, authentication, glass phosphor, optical feature information, up and down conversion.
