主　　题：Barium chlorapatite Nanoassemblies Phosphors Luminescence Room temperature coprecipitation 

摘      要：As an emerging host phosphor material, barium chlorapatite （Bas（PO4）3CI）, is attracting growing attention. However, rare earth-doped Bas（PO4）3CI phosphors have mainly been obtained via high temperature-based, energy-consuming techniques. In this contribution, we developed a straight- forward, facile room-temperature coprecipitation method in the presence of a specific amount of ethylenediaminetetraacetic acid disodium salt that provided Bas（PO4）3CI nanoparticles self-assembled to construct uniform Bas（PO4）3CI nanoassemblies （diameter： 80-120 nm） as well as rare earth Tb3＋- doped Bas（PO4）3CI：xTb3＋ nanophosphors. The nanoassemblies were transparent within the ultraviolet and visible spectral range. The Bas（PO4）3CI：xTb3＋ nanophosphors exhibited four emission peaks under 228-nm excitation, and the optimal doping amount of Tb3＋ was 4.0%. In contrast to traditional energy-consuming, high-temperature techniques, the facile room-temperature coprecipitation method developed here represents an attractive alternative route to obtain uniform Ba5（PO4）3CI nanoassemblies and Bas（PO4）3CI：xTb3＋ nanopbosphors that are candidate luminescent hosts.
