摘要

本文研究了不同浓度Ge27Ga9Se64玻璃纳米胶体溶液的制备及其非线性光学特性。利用开孔z扫描技术研究了它们的非线性吸收。通过改变溶液中溶质的浓度来调节材料的光学带隙。非线性随光学带隙的减小而增大，而带隙的减小又取决于纳米胶体溶液的浓度。

Investigation on nonlinear properties of Ga-Ge-Se nanocolloidal solutions

We present the preparation and nonlinear optical characterization of nanocolloidal solutions of Ge27Ga9Se64 glass with different concentrations. Their nonlinear absorption is studied using open aperture Z-scan technique. Optical band gap of the material is be tuned by changing the concentration of the solute in the solution. Nonlinearity increases with decrease in optical band gap which in turn depends on the concentrations of the nanocolloidal solutions.
