Abstract
A radiation shielding material for shielding against gamma radiation includes neodymium-doped zirconia nanoparticles in a matrix. The neodymium doped zirconia nanoparticles have a tetragonal crystal structure and an average size between about 25 nm to about 35 nm. The nanoparticles have a neodymium content in the range of about 1.5 mol % to about 3 mol % based on the total molar content of the zirconia nanoparticles. A method for the synthesis of neodymium-doped zirconia nanoparticles is provided. The method includes controlled metamorphosis of zirconia from monoclinic to tetragonal phase which results in a multifunctional shielding material having durability and high radiation absorption efficiency.
