title: Impact of yttria stabilization on Tb3+ intra-shell luminescence efficiency in zirconium dioxide nanopowders.
abstract: This paper reports the observation of Tb(3+) 4f-4f emission gain in ZrO2 nanocrystals stabilized by Y2O3 as the amount of stabilizer increases from 0% to 10% mol. The nanocrystals were obtained via microwave solvothermal technology. The photoluminescence properties of as-grown samples are investigated. The possibility of biological applications of the material is tested on living organisms (mice). The result indicates the potential use of the studied material as a luminescent nanomarker.
