Well-developed, idiomorphic one-dimensional (1D) crystals of fluorapatite (FAp) were successfully grown for the first time on a poly(ethylene terephthalate) (PET) substrate at 150 °C by the cooling of the KNO3-LiNO3 flux. The grown 1D FAp crystals were transparent- colorless, hexagonal prisms bounded by well-developed six-sided {101̄0} and flat {0001} end faces, and elongated in the (0001) directions. Their average size was relatively large, reaching about 5.2 × 0.5 μm. In addtion, the 1D FAp crystal was of very good crystallinity because no defects were observed in its lattice image by transmission electron microscopy. Furthermore, highquality, idiomorphic 1D crystals of FAp were tried to be grown directly on a PET substrate by the flux method. The PET surface was completely covered with aggregated FAp crystals, which were flowerlike in shape (hemisphere) with FAp rods radiating from a central nucleus.
