Abstract

Nd³⁺-doped LiTaO₃ is successfully derived by the sol-gel method. The host solution is prepared by mixing LiOC₂H₅ and Ta(OC₂H₅)₅ and different concentrations of 1.0, 2.0, and 3.0 mol% of Nd³⁺ are introduced. The films are deposited on SiO₂/Si substrate by spin coating and the powders are prepared by sintering the precipitation of the solution. XRD and micro-Raman studies show that the material displays good crystallization of pure trigonal phase of LiTaO₃. AFM and SEM studies reveal that the crystalline size is about several tens of nanometers for the films and a few hundred nanometers for the powders after an annealing at 600°C. Using the 488nm line of an Ar⁺ laser as an excitation source, photoluminescence of the powders is observed at 1.06μm, corresponding to the ⁴F_3/2 → ⁴I_{1 1/2} transition of Nd³⁺. The full width at half maximum is about 40nm.
