Paper Abstract

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.
