【摘要】 在ITO导电玻璃上,制作38层Z型细菌视紫红质(bR)的LB膜;控制平均转移比在0.93以上。测量了这个LB膜的紫外-可见吸收谱。利用Z扫描技术在输出飞秒激光,波长为400nm和800nm处对菌紫质LB膜的三阶非线性光学性能进行了研究。在800nm处,它的三阶非线性光学极化率为10-9esu,而在400nm处为10-8esu。这表明菌紫质LB膜在非线性光学器件方面具有潜在的应用前景。更多还原

【Abstract】 The thirty-eight layers Bacteriorhodopsin Langmuir-Blodgett film was prepared on ITO and the third order nonlinear optical properties of the film were investigated using Z-scan technique.The bacteriorhodopsin Langmuir-Blodgett multilayer film’s third-order nonlinear susceptibility((3) was measured at the wavelength of 400nm and 800nm.It was 2.5×10~-~9 esu at 800nm and 1.1×10~-~8esu at 400nm,respectively.It shows that the bacteriorhodopsin Langmuir-Blodgett multilayer film has a high third-order nonlinear optical properties just as the bacteriorhodopsin.更多还原
