FIG. 1.

(a) Single crystal fibers of YSZ pulled at 40 mm/h; (b) europium doped fibers pulled at 40 mm/h; and (c) europium doped fibers under 325 nm laser excitation at RT.

FIG. 2.

Raman spectra of: (a) YSZ (cubic); and (b) europium doped YSZ fibers (tetragonal).

FIG. 3.

SEM micrographs of longitudinal sections of an europium doped fiber pulled at 40 mm/h: (a) general view; (b) high magnification; and (c) EDS maps of Zr, Y, and Eu concentration along the fiber diameter.

Image of FIG. 4.
FIG. 4.

RT PL spectra of undoped and europium doped fibers pulled at 40 mm/h under 325 nm He–Cd laser excitation. For comparison the RT PL spectrum of a praseodymium doped fiber pulled at 40 mm/h is also shown (dashed line).

FIG. 5.

Comparison between the 14 K and RT PL and PLE spectra of the europium doped fiber.

Image of FIG. 6.
FIG. 6.

Temperature dependence of the luminescence for two excitation wavelengths, 325 nm (a) and 457 nm (b). The inset depicts the evolution of the integrated intensity of the overall luminescence with temperature.
