Encode a security sign in your product using our special phosphors and have customers and other stakeholders decode its authenticity by a simple flash of a mobile phone. Most anti-counterfeiting technologies applied to trace products during supply chain are expensive and in most cases can not be used by the end user.
The technologies that use  phosphors (security ink), rely on the fluorescent materials but more advanced ones use phospohors with afterglow properties. The lifetime of the emited afterglow light adds another security layer. The problem is that most of the afterglow phosphors require ultraviolet light (not safe) for excitation and also contain rare-earth materials.
We offer our special sustainable organic afterglow phosphors for product protection that can be excited by flashlight from a mobile phone. We also offer novel security ink that emits different colours depending on the wavelength of the illumination light.
Since the volume of online purchase has increased from the start of COVID-19, the possibility of the end user to easily authenticate the purchased products has become very important. LehMoSense offers this possibility at low cost.
