Abstract
A wavelength-shift composite light-storing powder and method of manufacturing and applying the same. Wherein, inorganic metal oxide and light-storing material containing rare earth elements are made to collide at high speed in an environment of extremely low temperature. The collision process makes said inorganic metal oxide to produce fusion reaction on surface of said light-storing material, that causes changes of lattice structure, to generate photon shift phenomenon and produce said wavelength-shift composite light-storing powder. Said composite light-storing powder is apt to engage cross-linked structure of thermoplastic polymer in a high temperature blending process, to achieve even distribution. Finally, through a filament process to produce successfully light-storing fibers capable of emitting lights of various wavelengths, to raise its heat resistance and wash durability.
