Ce, Pr, and La-doped gadolinium pyrosilicate Gd(2)Si(2)O(7) (GPS) single crystals were grown by the Czochralski and Top Seeded Solution Growth (TSSG) techniques for the first time. Formation conditions of different pyrosilicate phases were determined. X-ray luminescence integral intensity of Ce-doped GPS is about one order of magnitude higher in comparison with gadolinium oxyorthosilicate Gd(2)SiO(5):Ce (GSO:Ce). All samples demonstrate temperature stability of luminescence yield up to 400 K. (C) 2010 Elsevier B.V. All rights reserved.
