Dendrimer-based preparation and luminescence studies of SiO2 fibers doping Eu3+ activator in interstitial sites

“…Therefore, a combination of electrospinning method with sol-gel process is one appealing route to obtain 1D rare earth ions doped silica phosphor bers materials, 19 which can expand their applications in many elds, such as sensors, electronic and optical devices, catalyze and biology elds. 20 In this work, a large scale of one-dimensional Eu 3+ -doped SiO 2 bers have been conventionally synthesized by electrospinning technique combined with a sol-gel process and the position of Eu 3+ activator ions in SiO 2 matrix was discussed for the rst time to our knowledge. The dendrimer PVP could be regarded as so templates to crosslink silica molecule and its linear structure was assisted the orderly structure to form a brous morphology during electrospinning.…”

One‐Step Facile Synthesis and Luminescence Properties of Eu3+‐Doped Silica Nanowires

“…Nanowires, typically 1–100 μm long and 1–200 nm wide, are an important class of one‐dimensional nanomaterials and have been extensively studied for a long time; different kinds of nanowires have been prepared, including SiO 2 ,2 ZnO,3 and TiO 2 4. Among these materials, amorphous silica as an important kind of optical candidate material is of great interest because of its convenient synthesis methods, mechanical and thermal stability, chemical inertness, corrosion resistance, and efficient photoluminescence emission 5. It was also found that silica nanowires are suitable to be doped or coated with other functional materials,6 and it has been reported that among the Eu 3+ ‐doped materials, the luminescent quantum efficiency of nanowires was better than that of nanoparticles and bulk powders,7 which extends the applications of Eu 3+ ‐doped silica nanowires in the fields of luminescent devices and functional optoelectronic materials.…”
