Growth and Spectrum Properties of Ce: YVO4 Single Crystal

The 1.0% (atom fraction) Ce3+ doped YVO4 single crystal was grown by the Czochralski technology in a protective atmosphere. The absorption spectrum, emission spectrum and excitation spectrum of the crystal were measured. Three absorption peaks at 473, 557 and 584 nm were observed. The luminescent spectra indicate that strong blue-green-yellow light emission may be caused by a blue light excitation, indicating that the Ce:YVO4 crystal has potential application in creating complex white light, besides being used in optical devices. The transition mechanism is explained and also illustrated briefly.
