Optical markers in the service of quality assurance and authentication of lubricants and greases
Graphene Quantum Dots (GQDs) and Carbon Dots (CDs) are extremely small particles, typically at the nanoscale. The dots’ size and composition can be carefully manipulated in order to fine-tune their photoluminescence. These materials are particularly useful because of their tunable photoluminescence over a wide spectrum range, and prolonged photo- and thermal-stability. GQDs/CDs are favorable alternatives to fluorescent dyes.
Made from carbon sources, Graphene Quantum Dots (GQDs) are a non-toxic advanced material
The fluorescence colour can be tuned by changing the size, chemistry, or doping – creating unique optical fingerprints
GQDs absorb photons of light, then re-emit photons at a different wavelength. For example GQDs fluoresce in visible spectrum when exposed to UV light
GQDs have multiple potential applications, including biomedical, in-product authentication, tracing, materials field testing and more
