Luminescence properties of composite material Sr2MgSi2O7∶Eu2+,Dy3+/light conversion agent with multilayer structure
文献摘要：
In order to improve the red luminescent properties,Sr2MgSi2O7∶Eu2+,Dy3+ was selected as a blue persistent luminescent donor phosphor,while light conversion agent was utilized to tune the persistent luminescent spectra from blue to red.Composite red luminescent material Sr2MgSi2O7∶Eu2+,Dy3+/light conversion agent (SMED/LCA) was fabricated with light conversion agent and Sr2MgSi2O7∶Eu2+,Dy3+ at a certain mass ratio.SiO2 (Al2O3 or MgF2) were coated on the surface of SMED/LCA through heterogeneous deposition method.The structural and optical characteristics of the resulting samples were launched in terms of X-ray diffraction and emission spectrum as well as afterglow brightness.The results demon-strate that the emission spectrum exhibits two emission bands,and the peaks are located at around 470 and 615 nm.SiO2,Al2O3 and MgF2 are coated on the surface of SMED/LCA like a protective shell to maintain its stability and luminescent properties,the afterglow initial brightness is still up to 0.37 cd/m2 and the afterglow color purity calculated from CIE color coordinates is basically unchanged.
