Europium luminescence in silver and gold nanoparticles co-embedded phosphate glasses: judd-ofelt calculation

Some europium ions (Eu3+) activated magnesium-zinc-sulfophosphate glasses with the silver (Ag) and gold (Au) nanoparticles (NPs) co-embedment were prepared via the melt-quenching method. The as-prepared samples were characterised using different analytical techniques to determine the effect of vario...
