PHOTOLUMINESCENT NANOCRYSTAL BASED TAGGANTS

摘要

A taggant for marking a target through the use of a carrier or a projectile loaded on a firing device and methods for fabricating the same are disclosed. The taggant including photoluminescent semiconductor nanocrystal(s) materials incorporated in a carrier or projectile. The photoluminescent semiconductor nanocrystal(s) materials may be encapsulated in a medium for facilitating marking of the target.
