Nonlinear optical properties of solutions of heavy fullerenes in the near-ultraviolet region
Tóm tắt
Nonlinear optical properties (particularly optical limiting) are determined for solutions of heavy fullerenes C76 + C78 + C84 + C90 + …, in the near-ultraviolet region (λ ≈ 280 ± 7 nm). It is shown that no optical limiting is observed in solutions of light fullerenes (C60 and C70), but found in solutions of water-soluble fullerenol-d (a mixture of oxypolyalcohols of fullerene C60-C60(OH)
n1O
n2, with their sodium salts) based on light fullerenes.
