Yttria stabilized zirconia single crystal fibers doped with europium ions were developed envisaging optical applications. The laser floating zone technique was used in order to grow millimetric high quality single crystal fibers. The as-grown fibers are completely transparent and inclusion free, exhibiting a cubic structure. Under ultraviolet ͑UV͒ excitation, a broad emission band appears at 551 nm. The europium doped fibers are translucent with a tetragonal structure and exhibit an intense red

The fingerprint transition lines between the 5 D 0 and 7 F J͑0-4͒ multiplets of the Eu 3+ ions are observed with the main emission line at ϳ606 nm due to 5 D 0 → 7 F 2 transition. Photoluminescence excitation and wavelength dependent the photoluminescence spectra confirm the existence of different Eu 3+ optical centers.
