Abstract
The UV absorption edge of YVO 4 crystal with a slight yttrium excess grown by Czochralski (CZ) technique, after annealing in O 2 atmosphere, was compared with oxygen deficiency-free YVO 4 crystals grown by the top seeded solution growth (TSSG) technique. The measurements show that the TSSG crystal has higher transparency in near-UV than the CZ sample, demonstrating a better near-stoichiometric composition in the TSSG-YVO 4 single crystal.
