1. A gamma radiation shielding material, comprising:
a matrix material comprising neodymium-doped zirconia nanoparticles, wherein the neodymium-doped zirconia nanoparticles are dispersed within the matrix material,
wherein the neodymium-doped zirconia nanoparticles have:
a tetragonal crystal structure,
a neodymium content of from about 1.5 mol % to about 3.0 mol % based on a total molar content of the zirconia nanoparticles, and
an average size in a range of about 25 nm to about 35 nm.
