摘要

In this study, stoichiometric lithium niobate (LiNbO₃) single-crystal fibers were grown by the laser-heated pedestal growth (LHPG) method using different compositions with [Li₂CO₃]/[Nb ₂O₅]=48.6:51.4, 50:50, 55:45 and 58:42 seeds. X-ray/CCD and ICP-AES were used to confirm the crystalline structure and the composition of the fibers, respectively. Electron spectroscopy for chemical analysis (ESCA) was used to analyze the [Li]/[Nb] ratio along the axis of the fibers. Based on these measurements, the growth mechanism that produces stoichiometric LiNbO ₃ fibers from stoichiometric feeding rods was investigated. The results show that the growth of stoichiometric LiNbO₃ fibers using the LHPG method followed the equilibrium phase diagram concept.
