High quality Er3+/Nd3+ co-doped Lutetium lithium fluoride (LiLuF4) single crystals with a size of φ10 mm × 90 mm were grown by a Bridgman method. XRD, absorption spectra, and fluorescence spectra of these single crystals were studied. Enhanced mid-IR emission of 2.7 μm, and weakened up-conversion emission of 550 nm and down-conversion emission of 1.5 μm emission were observed in Er3+/Nd3+ co-doped LiLuF4 single crystals under an exciting light of 808 nm, as compared with Er3+ singly-doping. Meanwhile, Mid-IR emissions of 3.6 μm and 4.2 μm were also observed in Er3+/Nd3+ co-doped LiLuF4 single crystals. Energy transfer efficiencies between Nd3+ and Er3+ ions were calculated and the decay curves of the 1.06 μm for Nd3+ emission and 1.5 μm for Er3+ emission were analyzed with a modified Inokuti-Hirayama model. The large energy transfer efficiency of 95.6% and excellent optical properties indicate that this Er3+/Nd3+ co-doped LiLuF4 single crystal is a potential candidate for the applications in mid-IR laser.
