Methods and systems for an emissive fiber capable of being used for making emissive fabric by providing an optical fiber having a core and and embedding up conversion particles into at least one of the cladding and core to produce an emissive fiber that emits visible light when excited by light from near infrared light source that excites the up conversion particles. The optical fiber can have a core index of refraction that is greater than or less than the refractive index of the cladding for near infrared light or an index difference between the core and cladding of zero. Plural optical fibers are intertwined to produce an emissive fabric, wherein coupling a light source with the emissive fibers transmits a light beam through the fiber to excite the up conversion particles to emit visible light. The up conversion material can be embedded into the core, the cladding, or both.
