摘要：
CaTiO3:Re3+(Re=Eu, Dy) phosphors were synthesized by hydrothermal method. XRD, SEM and PL spectra were used to characterize the samples. The crystallinity and luminescent properties of CaTiO3:Re3+ phosphors reach optimal state when pH=12, and SEM analysis indicates that the powder has good dispersion when the particle size is about 450 nm. The optimum concentration of rare earth ions is determined. The emission peaks of CaTiO3:0.12Dy3+ locate at 485 nm (blue) and 576 nm (yellow) under 353 nm excitation. The intensity ratio of the blue-yellow emission peaks (IY/IB) produced by the two transitions can be regulated via adjusting Dy3+ concentration. Therefore, luminescent color of CaTiO3:Dy3+ phosphor can be tuned by changing Dy3+ concentration. © 2018, Science Press. All right reserved.
