Abstract
A rare earth (RE) downconverting phosphor composition may contain two or more lanthanide materials each having a host and at least one downconverting emitter. Each lanthanide material emits a detectable electromagnetic radiation emission peak at an intensity, which is proportional to the amount of emitter present, upon excitation with an absorbable electromagnetic radiation, the emitted radiation having a lower energy, i.e., a longer wavelength than the absorbable radiation. One or more ratios of the intensities of the emitted detectable electromagnetic radiation may be used to uniquely identify the composition. Alternatively, the RE downconverting phosphor composition may contain a lanthanide material having a host and at least two emitters. The lanthanide material emits at least two different detectable electromagnetic radiation emission peaks each at an intensity upon excitation with an absorbable electromagnetic radiation, the emitted radiation having a lower energy, i.e., a longer wavelength than the absorbable radiation.
