UV Visible Fluorophore

The security market for authentication of your valuable products has been consistently grown in the world business transaction. NANOCMS’s fluorophores are very suitable in variety of security area for users to need this type of marking. They can easily check through the aid of a fluorescence scanner connected to a signal transmitter. The marked papers with fluorescent inks provide particular protection against unauthorized duplication using a commercial color copier. Also the original and forgery as well as any counterfeit can be distinguished by difference in being fluorescent or not. This is why NANOCMS’s fluorophore series are recommended for this purpose since the copiers are not capable of transferring fluorescent features.

1. UVA Visible

UVA fluorescent materials are widely known as fluorophores which are excited by ultra-violet ray having 320nm to 400nm (UVA: standard excitation at 365nm). The big difference with the commercial visible fluorescent pigments is possible to be printed as a covert security feature because of colorless in daylight but fluorescence by UVA excitation. NANOCMS supplies 5 organic pigments:

*) Above fluorescence colors are for your reference only and may different from the original emitting shade.

2. UVB & UVC Visible

UVB&C fluorescent materials have a very unique fluorescent property which is only excited by UV ray having 200nm(UVC: standard excitation at 254nm) to 320nm(UVB: standard excitation at 312nm) and not excited at UVA such as 365nm. So, currently increasing its interest to apply as a covert feature as differentiated with UVA fluorescent materials. NANOCMS supplies 3 organic pigments:

*) Above fluorescence colors are for your reference only and may different from the original emitting shade.

3. UVA & UVC Visible (Bi-fluorescence)

Until now, there have been many attempts to get bi-fluorescent inks as high-level anti-counterfeiting elements in fluorescent security area. But it is very difficult to present due to no supplying of reliable shortwave fluorescent materials and overlapping phenomenon of excitation wavelength. To meet this market demand, NANOCMS can provide the organic pigments:

*) Above fluorescence colors are for your reference only and may different from the original emitting shade.
