Copper mediated optical properties of rare earth doped amorphous materials

Abstract

Borophosphate based glass materials having rare earth, shows promising optical photonic and biomedical applications. Here in the current report, Dy3+ ions and CuO is co-doped in Borophosphate glass and new hybrid glasses with different properties were prepared by using melt-quenching method. The intensities of 4f intrabands transitions of rare earth ions changed by the addition of metallic Cu nanopartciles (NPs). Photoluminescence spectroscopy of Borophosphate glass co-doped with Dy3+ ions and Cu nanoparticles revealed the dynamic decay of Dy3+ ions due to the influence of Cu plasmonic nanoparticles. The optical properties of these glasses were characterized by different methods as UV-Vis, Raman, PL (photoluminescence), FTIR and XRD. The results show the absorption and luminescence spectroscopy also the excited state lifetime that gives the optical properties of the glass.
