The spectroscopic performance of Er doped glass at 0.55 μm emission contain different nanoparticles NPs have been comparatively evaluated. Glass containing 1.0 mol % of Er doped with different NPs (Ag, Co and Fe ) have been prepared using melt quenching technique. X-ray diffraction analysis reveals the all the prepared samples are amorphous. The UV-Vis absorption spectra of all glasses show several prominent peaks at 525 nm, 660 nm, 801nm, 982 nm and 959 nm due to transition from ground state I15/2 to different excited of H11/2, F9/2, I9/2, I11/2, and I13/2. The emission of Er at 0.55 μm for glass contain Ag NP shows significant enhancement about 3 folds up to 0.6 mol%. On the other hand, the emission of Er at 0.55 μm for glass containing Fe NPs and Co NPs intensely quench probably due to the energy-transfer from Er ion to NPs and magnetic contributions.
