- In this paper YVO4:Dy3+ was synthesized via solid state method at 1100°C and effects of different quantities of SiO2 particles on microstructure and photoluminescence properties were investigated in details. To study the microstructure and properties of these composites XRD, SEM, TEM, HRTEM, XPS and PL equipments were employed. It was found that via addition of SiO2 particles to YVO4:Dy3+ phosphors, strong bonding is made between SiO2 particles and phosphors. Furthermore, based on stronger electronegativity of Si 2p element compared to Y 3d and V 2p elements, increase of SiO2 causes the increase of binding energy. Moreover, this research showed that the addition of 10 wt% SiO2 particles to YVO4:Dy3+ material enhances the excitation and emission luminescence properties, significantly. Further increase of SiO2 particles results in suppress of emission intensity.
