Article Description

1 at % Pr-doped YO single-crystal fibers were prepared using a laser-heated pedestal growth method. The emission and excitation spectra of the fibers were measured. The emissions of 4f-4f transitions from D to the H and H states are found at 620 and 720 nm, respectively. The P , P , I , and P 4f-4f absorptions are observed at 456, 472, 482, and 492 nm, respectively. A 4f-5d absorption band is detected at 288 nm. Photoconductivity measurements show that the 4f-5f transition of Pr around 285 nm produces a direct photocurrent. Taking the onset of photocurrent to be at 320 nm, the ground state of Pr is determined at 1.7 eV above the valence band of the host. © 2008 Pleiades Publishing, Ltd.
