Embodiments of luminescent phosphor-containing materials include a medium and particles of a phosphor compound dispersed in the medium. The phosphor compound includes a host lattice comprising at least one alkaline earth element, manganese, and europium (e.g., divalent manganese and divalent europium). Embodiments of methods for producing such a phosphor-containing material include preparing a phosphor compound that includes the phosphor compound particles, and dispersing the particles in the medium to produce the phosphor-containing material. The material may then be incorporated into an article. Embodiments of a method for identifying a phosphor-containing material incorporated with an article include exposing a portion of the article to exciting radiation (e.g., light produced by a blue diode), and determining whether a detected emission produced as a result of the exciting radiation indicates a manganese emission following a europium absorption for at least a first time period after termination of the exposing step. |
