The use of security features, such as luminescent inks, has increased significantly in an attempt to prevent fraud and counterfeiting of materials and goods. Obvious applications of these inks include banknotes, branded goods, drug packaging and food security. Security inks can either show up overtly or be covert, with the latter driving the luminescence further from the visible spectral region into the ultraviolet (UV) and near infrared (NIR) regions. These are regions where light sources are not so common. The use of the luminescence lifetime on top of the wavelength signature adds an extra parameter that can be interrogated.
