Enhanced luminescence properties of CaTiO3:Pr3+ phosphor with addition of SiO2 by solid-state reaction

• Red phosphors CaTiO3:Pr3+ with addition of SiO2 were prepared by solid-state reaction technique.
• The crystalline phase, surface morphology and luminescence properties of the samples were identified by X-ray diffractometer, transmission electron microscope and photoluminescence spectrometer, respectively.
• CaTi0.5Si0.5O3:Pr3+ exhibited the optimal luminescence properties.
• It provides a novel strategy to prepare other phosphors with excellent luminescence properties in the same scale by soft chemical route.

Red phosphors CaTiO3:Pr3+ with addition of SiO2 were prepared by solid-state reaction technique (SS). The effect of SiO2 on the crystalline phase, surface morphology and luminescence properties of CaTiO3:Pr3+ was studied by X-ray diffractometer, transmission electron microscope, brightness meter and photoluminescence spectrometer, respectively. The results indicated that the content of SiO2 has influence on luminescence intensity, initial brightness and persistent time of samples. The red phosphor CaTi0.5Si0.5O3:Pr3+ exhibited the optimal luminescence properties.
