Abstract
(EN)
Disclosed is a plastic product for which authenticity can be determined comprising: a base material made of a plastic material; and a light emitting material which is included in the base material and emits emission light including a second wavelength with respect to incident light including a first wavelength, wherein the determination of authenticity is performed by detecting the emission light after irradiating the incident light. According to the present invention, the authenticity of the plastic product can easily be determined by a simple method of detecting an emission spectrum emitted from the plastic product.
(FR)
L'invention concerne un produit en plastique pour lequel l'authenticité peut être déterminée, comprenant : un matériau de base constitué d'un matériau plastique ; et un matériau électroluminescent qui est inclus dans le matériau de base et émet une lumière d'émission comprenant une seconde longueur d'onde par rapport à une lumière incidente comprenant une première longueur d'onde, la détermination de l'authenticité étant effectuée par détection de la lumière d'émission après irradiation de la lumière incidente. Selon la présente invention, l'authenticité du produit en plastique peut être facilement déterminée par un procédé simple de détection d'un spectre d'émission émis à partir du produit en plastique.
