摘　　要：The nonlinear refractive indexes n 2 for the ethanol solutions of 1,10-phenanthroline (2.0×10 -3 mol·L -1), [bis(1,10-phenanthroline) lanthanum (Ⅲ)] nitrate (1.0×10 -3 mol·L -1), and [nitrato-fluoracil-bis (1,10-phenanthroline) lanthanum (Ⅲ)] nitrate (1.0×10 -3 mol·L -1) are first measured, the third-order nonlinear optical susceptibilities χ (3) and <γ> are calculated, and the mechanisms of the third-order optical nonlinearities enhanced by lanthanum (Ⅲ) are discussed preliminarily.The nonlinear refractive indexes n 2 for the ethanol solutions of 1,10-phenanthroline (2.0×10 -3 mol·L -1), [bis(1,10-phenanthroline) lanthanum (Ⅲ)] nitrate (1.0×10 -3 mol·L -1), and [nitrato-fluoracil-bis (1,10-phenanthroline) lanthanum (Ⅲ)] nitrate (1.0×10 -3 mol·L -1) are first measured, the third-order nonlinear optical susceptibilities χ (3) and <γ> are calculated, and the mechanisms of the third-order optical nonlinearities enhanced by lanthanum (Ⅲ) are discussed preliminarily.
