Shielding properties of Li 2 B 4 O 7:Dy 3+,Yb 3+glass containing copper nanoparticles

Glass matrices of Li 2 B 4 O 7 doped with Dy 3 + , Yb 3 + and Cu were synthesized by melt quenching technique using different concentration of copper nanoparticles. The study and analysis are centered in shielding radiation. The samples amorphous nature was corroborated by X -Ray diffraction (XRD) and nanoparticles size distribution was obtained by transmittance electron microscopy (TEM). Optical characterizations used were absorbance and photoluminescence emission (PL). Radiation shielding theoretical properties: mass attenuation coefficient (MAC), half value layer (HVL), tenth value layer (TVL), mean free path (MFP) and effective atomic number (Zeff) are obtained using Phy-X/PSD software and analyzed for future applications in radiation security.
