Abstract
A photoluminescent marking that includes a photoluminescent layer and at least one functional overlayer is disclosed. The photoluminescent layer comprises at least one type of photoluminescent material. The at least one functional overlayer is adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking or to prevent the observability with the naked eye of a printed message on the marking. Also methods of making and using the inventive photoluminescent marking are disclosed.
Claims39
A photoluminescent marking comprising:
- a photoluminescent layer comprising at least one type of photoluminescent material;
- and
- at least one functional overlayer disposed over at least the photoluminescent layer, the at least one functional overlayer being adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking.
A photoluminescent marking comprising:
- a photoluminescent layer comprising at least one type of photoluminescent material;
- and
- at least one functional overlayer disposed over at least the photoluminescent layer, the at least one functional overlayer being adapted to selectively filter wavelengths of radiation to prevent the observability with the naked eye of a printed message on the marking.
A method of fabricating a marking, the method comprising:
- forming a photoluminescent layer comprising at least one type of photoluminescent material;
- applying at least one functional overlayer to the photoluminescent layer, the at least one functional overlayer being adapted to selectively filter wavelengths of radiation;
- and
- incorporating the photoluminescent layer and the at least one functional overlayer onto or into at least a portion of the marking.
A method for marking an object, the method comprising:
- applying a photoluminescent marking onto or into at least a portion of the object, the photoluminescent marking comprising a photoluminescent layer and at least one functional overlayer that is adapted to selectively filter wavelengths of radiation.
A method for identifying an object, the method comprising:
- detecting a potential emission signature from a photoluminescent marking previously applied onto or into at least a portion of the object, the photoluminescent marking comprising:
- a photoluminescent layer, and
- at least one functional overlayer that is adapted to selectively filter wavelengths of radiation, and
- wherein the potential emission signature is subsequently compared to a known emission signature.
