Nanoparticles (NPs) size dependent enhancement of the infrared-to-visible frequency up-conversion (UC) and absorption coefficient in silver NPs embedded Er 3+ doped tellurite glasses on pumping with the 976 nm radiation have been i nvestigated. The rate equations derived from the 4-level model devel...
