Stability of red rare earth luminous fiber emission spectra

Rare earth strontium aluminate luminous fiber is a novel functional fiber. In order to investigate emission light color stability of the rare earth luminous fiber containing red organic fluorescent pigment, several kinds of rare earth strontium aluminate luminous fibers were prepared by using rare-earth strontium aluminate as the rare-earth luminescent material and fiber-forming polymers such as polymer polyethylene terephthalate (PET) as a matrix and combining them with red organic fluorescent pigment as well as functional additives. Fluorescence spectrophotometer was used to characterize the resulting samples. Results showed that the shape and the peak of emission showed little change, but the emission intensity became weaker as the treatment time increased.
