Abstract: 
The enhanced luminescent properties of Tb3+ and Gd3+ doped ZrO2 nanoparticles (NPs) modified by coating with a shell were investigated. The pure cores, synthesized by a hydrothermal process, are in a high quality tetragonal phase and a monoclinic phase with an average size constant of similar to 7 +/- 2 nm. The thickness and composition of the SiO2 shell can make a difference to the luminescent properties of the NPs. The intensity of the green light emission was enhanced remarkably after coating the active shell (containing Gd3+) around the ZrO2: Gd3+, Tb3+ NPs. The increased photoluminescence (PL) intensity is attributed to a reduced non-radiative recombination based on a longer luminescence decay time and an energy transfer from the Gd3+ in the shell to the adjacent Tb3+ ions.
