A luminescent material comprising a luminescent benzothiazole, an article comprising a security feature, and a method of forming a luminescent particle comprising a luminescent benzothiazole

摘要

Provided herein are luminescent materials comprising the luminescent phosphor compound, articles comprising security features, and methods of making the luminescent phosphor compounds. In one embodiment, the luminescent material comprises a medium and luminescent particles. The luminescent particle comprises a luminescent benzothiazole having a ureido bond. The luminescent benzothiazole has a peak intensity within a wavelength of about 555 to about 630 nm in response to excitation by electromagnetic radiation of a wavelength of about 366 nm.
