Abstract :
Pure and Yb-doped Ca9Y(VO4)7 (CYVO) single crystals were grown using the Czochralski method. Their crystal structure was determined using powder diffraction and the defect structure was characterized using high-resolution diffraction. The undoped crystal is found to be composed of a transparent and an opaque parts. In the latter, yttrium-rich inclusions were detected. Spectral-kinetic characteristics of Yb3 -doped crystals is reported.
