This paper deals with a synthesis of a new ionising radiation attenuation composite material from Lu2O3 - Bi2O3 nanoparticles structure, that has never been described yet. The paper describes the preparation of Lu2O3 - Bi2O3 nano- and microparticles by three methods: a self-combustion synthesis, a solid-state method and a coprecipitation method. Polymer solution was prepared from Lu2O3 - Bi2O3 nanoparticles and Polyvinyl Butyral. Afterwards, nanofibers were processed by an electrospinning method from PVB - Lu2O3 - Bi2O3 polymer solution. PVB - Lu2O3 - Bi2O3 nanofibers were characterised and their X-Ray attenuation effect was tested. This paper proceeds from one of the author’s bachelor thesis.

Keywords: Metal oxides nanoparticles, nanofibers, X-Ray, lead-free materials, PVB
