Abstract:

Pr:GdVO4crystals were grown by Czochraliski method. The structure of the crystals were studied by XRD, and the results confirmed that their structure were the same with the pure GdVO4crystal. The absorption spectrum had been measured from 400 nm to 3000 nm at room temperature. We find that the strength of each absorption peak is much stronger in σ-absorption-spectrum, so we had better do laser experiments while incident ray and the direction of electric complexor plumb with ray axis. The fluorescence excited by 404 nm laser was recorded separately. We find that there is a wide and powerful fluorescence-emission band in visual field (604 nm, 616 nm), corresponding with1D2→3H4. Comparing fluorescence spectra of different doping-content crystals, the fluorescence intensity appeared as follows: 0.5%>0.7%>0.32%.
