Substrate including scintillator materials, system including substrate, and method of use

Abstract

A substrate can include at least two scintillator materials that are mixed at a predetermined ratio. In an embodiment, the scintillator materials can have a decay time difference of at least 50% when exposed to a same radiation source. In another embodiment, the scintillator materials can have a maximum emission wavelength difference of at least 25 nm when exposed to a same radiation source. At least one of the scintillator materials has a decay time of at most 10 μs. A system can include the substrate and a logic element configured to determine an identity represented by the substrate. A method can include generating an electronic pulse in response to the substrate being exposed to a radiation source; and analyzing the electronic pulse to determine an identity represented by the substrate.
