Abstract:A series of tungstate double perovskite Ca3WO6 doped with Tb3+ was prepared by a combustion process using urea as a flux. The crystal structure identification of Ca3WO6:Tb3+ phosphors was done using X‐ray diffraction patterns, and a monoclinic structure was discovered. The Fourier transform infrared spectrum of Ca3WO6:Tb3+ displayed characteristic vibrations of tungstate bonds. Under 278 nm excitation, Ca3WO6:Tb3+ exhibited intense downconversion green emission, which corresponded to the 5D4–7FJ (J = 4,5) tran… Show more
