초록
Red long persistent phosphors of CaZrO₃: Pr was synthesized by a solid reaction method. CaCO₃ and ZrO₂wereused as hosting materials and Pr was doped as luminescence center element, and B₂O₃was used as flux. The XRD patternand 590~700 nm. Phosphor samples were synthesized with B₂O₃flux concentration of 1, 5, 10 %, and luminescent peak ofmaximum intensity at 494 nm was obtained for 1 % B₂O₃. Luminescent peak of red color at 620 nm was of highestintensity for 10 % B₂O₃.
