英文摘要	The novel Dy3+ singly doped and Dy3+/Nd3+ co-doped fluoride glasses have been synthesized, and their fluorescence properties have been monitored under 808 nm excitation. The addition of Nd3+ leads to a higher emission peak, and a longer lifetime of 270 mu s for Dy3+ 2.9 mu m emission, benefited by the low Off content (0.032 cm(-1)) host and effective energy transfer of Nd3+: F-4(5/2), H-2(9/2)-> Dy3+: F-6(5/2) with a energy transfer coefficient of 3.0 x 10(-46) cm(6)/s. Radiative and emission parameters were calculated based on the Judd-Ofelt theory, which shows that the Dy3+/Nd3+ co-doped sample possesses a high calculated spontaneous transition probability (38.3 s(-1)) together with a large emission cross section (5.22 x 10(-21) cm(2)). The FWHM is as wide as 260 nm, indicating it is suitable for tunable laser medium. These results prove the fluoride glass could be used as a potential candidate for compact and efficient eye safe mid-IR lasers.
