Spectral features of Ho3+ -doped boro-phosphate glass-ceramics: Role of Ag nanoparticles sensitization

The development of the metallic nanoparticles-sensitised and lanthanides-doped multi-functional luminescent glass-ceramics (GCs) for advanced applications remains challenging. In this perception, the role of varying silver nanoparticle (Ag NP) concentration on the structures, microstructures and opt...
