Ag nanoparticles localised surface plasmon field regulated spectral characteristics of Ho3+-doped phosphate-based glass-ceramic

The holmium ion (Ho3+)- activated phosphate-based glass-ceramics with silver nanoparticles (Ag NPs) inclusion were prepared using the standard melt-quenching. The samples were characterised to evaluate the effects of different Ag NPs contents on their structure, microstructure and optical properties...

description The holmium ion (Ho3+)- activated phosphate-based glass-ceramics with silver nanoparticles (Ag NPs) inclusion were prepared using the standard melt-quenching.

The FTIR and Raman analyses showed the modification of the glass-ceramics network structure due to the embedment of Ag NPs. The TEM and HRTEM images together with the localized surface plasmon resonance (LSPR) absorption bands of the glass-ceramics confirmed the existence of Ag NPs inside the host matrix. The complex impedance analyses of the glass-ceramics suggested the glassy phase dominance in the host network.
