Shiny, HAp(py) crystals: Luminescent, colloidal, F-substituted, hydroxyapatite (FHAp) nanocrystals have been synthesized by rare-earth-ion doping, which showed green emission in solutions and films and red emission in a polymer matrix. Due to the wide availability and excellent mechanical and biologically compatible properties, these luminescent nanocrystals may find applications in biological labeling, luminescent polymers, and so forth.
