Luminescence of neodymium ion-activated magnesium zinc sulfophosphate glass: role of titanium nanoparticles sensitization

A series of neodymium ion (Nd3+)-activated magnesium zinc sulfophosphate glasses sensitized with various contents of titanium nanoparticles (Ti NPs) were prepared via the melt-quenching method and characterized. The influence of Ti NPs on the optical characteristics of the glasses was determined. Th...
