The Nd³⁺, Yb³⁺ singly doped and Nd³⁺ /Yb³⁺ co-doped lithium aluminum silicate glasses are fabricated by using a conventional melt quenching technique in air atmosphere, with the molar composition of (60-a-b)SiO₂-3Al₂O₃-20Li₂O-12MgO-5CaO-aNd₂O₃-bYb₂O₃ (with a=0, 0.25, 0.5, 1 and b=0,2). The Spectroscopic properties of 1.0 μm emission and Luminescence lifetime in Nd³⁺ /Yb³⁺ co-doped lithium aluminum silicate glasses are investigated under 808 nm excitation. The Judd–Ofelt theory is used to study the spectroscopic properties of Nd³⁺ . Meanwhile, the emission cross-section of Yb3+ are obtained by using the reciprocity method. A broad emission band from 950 to 1,100 nm is detected when the Nd³⁺ /Yb³⁺ co-doped in lithium aluminum silicate glasses excited by 808 nm LD. The energy transfer process from Nd³⁺ →Yb³⁺ co-doped in lithium aluminum silicate glasses is described in this paper.
