In this study, single-phase Ba1.3Ca0.7SiO4: x mol%Dy3+ (x = 0-5) phosphors were prepared by solution combustion method. X-ray diffraction pattern showed that the Ba1.3Ca0.7SiO4: x mol%Dy3+ phosphors are polycrystalline with predominant hexagonal T-phase structure. The scanning electron microscope images show that the synthesized nano powder consists of small particles in the order of few microns that are uniformly distributed over the surface having clear grain boundaries but changed to spongy shape morphology at the high content of Dy3+ ions. The ultraviolet-visible analysis displayed that the percent reflectance in the UV-region to be dependents on Dy3+ concentration. The estimated optical bandgap varies between 3.60 and 3.85 eV. The Chen method was used to analyses the TL kinetics of the two glow peaks observed at 409K and 523K for the samples doped with a different molar concentration of Dy3+. Photoluminescence spectra revealed strong emissions at 482 and 576 nm and weak once at 710 nm which were assigned to 4F9/2 →6H15/2, 13/2, 11/2 transitions of Dy3+ ions, respectively. The CIE color coordinates confirmed that the luminescence color of Ba1.3Ca0.7SiO4: Dy3+ was tuned from blue to white with an increase in the Dy3+ molar content.
