Abstract:
The present invention relates generally to encoding samples. More specifically, it relates to barcodes and compositions involving upconverters and methods including them. In a composition aspect of the invention, a composition comprising two or more lanthanide materials is provided. Each lanthanide material comprises a host, an absorber, and an emitter, and the materials emit detectable electromagnetic radiation upon excitation with absorbable electromagnetic energy. One or more relative ratios of emission intensities uniquely identify the composition.
