摘要:
The present invention relates to a metal fluoride red phosphor and an application of the phosphor as a light emitting element, the metal fluoride red phosphor having a tetragonal crystal structure of a novel composition, and emitting light in the red color wavelength by being excited by ultraviolet rays or a blue excitation source, thereby being usefully applicable to a light emitting element such as a light emitting diode, a laser diode, a surface emitting laser diode, an inorganic electroluminescence element, and an organic electroluminescence element.
摘要:
A composition may include an aqueous base and at least one identifying additive. The at least one identifying additive may include an alkaline earth metal compound and a fluorescence activator. The at least one identifying additive may be configured such that the composition emits fluorescent light having an identifying characteristic different from a characteristic of a surface against which the identifying characteristic is viewed. A composition may include an aqueous base and at least one identifying additive including an alkaline earth metal compound and a fluorescence activator including at least one other inorganic element. The at least one identifying additive may be configured such that the composition emits fluorescent light having an identifying characteristic. A label or packaging for identifying at least one of an object and a source of the object may include a composition including at least one identifying additive associated with a surface associated with the label or packaging.
