RARE EARTH COMPLEXES, RARE EARTH COMPLEX SYNTHESIS PROCESS, USE OF COMPLEXES, USE OF COMPLEX IN LIGHTING DEVICES, PRODUCT OF LIGHTING UNDERSTANDING COMPLEX, USE OF COMPLEX AND KIND DEVICES DETECTION OF SUBSTANCES UNDERSTANDING RARE EARTH COMPLEX. Trivalent rare earth ions (Nd ^ + 3 ^, Gd ^ + 3 ^, Eu ^ + 3 ^, Tb ^ + 3 ^ and Tm ^ + 3 ^) coordinated to organic ligands show emission in the infrared region and / or visible, which have application in Safety Markers applied in polymers, fabrics, paper, inks, fuel and in light emitting organic devices (OLED). Such Light Emitting Organic Devices (OLED) produced from these Rare Earth complexes, similar to the complexes, have a unique combination of emission colors from the use of Rare Earth complexes of various metals; featuring a unique "fingerprint"; which makes counterfeiting the product in which this Security Marker is used virtually impossible because it combines emerging technology that is difficult for the general public to access; with the properties of the emitting compounds developed and produced by the company; that allow you to create custom "fingerprints" for each customer.
