This paper deals with a synthesis of new ionising radiation attenuation composite material from Lu2O3 - Bi2O3 nanoparticles structure, that has never been described yet. The describes the preparation nano- and microparticles by three methods: self-combustion synthesis, solid-state method coprecipitation method. Polymer solution was prepared Polyvinyl Butyral. Afterwards, nanofibers were process...
Ytterbium disilicate powders were synthesized by cocurrent chemical coprecipitation method. The influence of Si/Yb molar ratio and calcination temperature on compositions structures Yb2Si2O7 products investigated. formation mechanism thermal behavior precursor as well the phase evolution also discussed in depth. Results show that pure β-Yb2Si2O7 with nanoscale size can be obtained from 1.1 afte...
Titanium dioxide nanopowders doped with different amounts of Fe ions were prepared by coprecipitation method. Obtained materials were characterized by structural (XRD), morphological (TEM and SEM), optical (UV/vis reflection and photoluminescence, and Raman), and analytical techniques (XPS and ICP-OES). XRD analysis revealed rutile crystalline phase for doped and undoped titanium dioxide obtain...
