Abstract
The present invention relates to the use of nanocompounds as non deactivable security markers comprising a charge-transfer complex of at least two different size metal atomic quantum clusters (AQCs). These nanocompounds are luminescent, particularly fluorescent after external excitation. The invention also relates to security documents, articles or elements incorporating these markers as well as to a method and a system for detecting the same.
