摘要：

Tm3+/Yb3+ codoped transparent glass ceramic containing beta-PbF2 nanocrystals was successfully prepared. After thermal treatment, emissions from the (1)G(4) state of Tm3+ excited by 980 nm laser were greatly quenched by cross relaxation and the 700 nm luminescence from Tm3+:F-3(2,3) -> H-3(6) transition was strongly enhanced. A nearly monochromatic red luminescence band was observed. Based on the luminescence decay curves and Judd-Ofelt analysis, the strengthened cross relaxation played an important role in such phenomenon. (C) 2012 Optical Society of America
