Synthesis and luminescence properties of some Ce3+ doped silica sols
Ce -doped silica sols samples were prepared by acid, or two steps catalyzed sol-gel process, at different concentration of Ce3+ dopant. As silica precursors, tetraetoxysilane, or tetrametoxysilane, or a precursors mixture consisting of tetraetoxysilane and isobuthyltrietoxysilane, were used. By UV e...

| Tartalmi kivonat: | Ce -doped silica sols samples were prepared by acid, or two steps catalyzed sol-gel process, at different concentration of Ce3+ dopant. As silica precursors, tetraetoxysilane, or tetrametoxysilane, or a precursors mixture consisting of tetraetoxysilane and isobuthyltrietoxysilane, were used. By UV excitation, all synthesized samples presented strong luminescence emission with maxima situated at ~ 386 nm. Regarding the emission efficiency, better results were achieved at lower Ce3+ concentrations. Depending on precursors nature, a favorable influence had the use of precursors mixture. |
