Nonlinear optical properties of the vanadium dioxide films

In this work the properties of vanadium oxides films are investigated for optimizing their nonlinear optical coefficients. Vanadium oxides films are studied obtained by pyrolysis of vanadyl acetylacetonate. Experimental determination of parameters of films was carried out by measuring the dependencies of reflectivity and conductivity with temperature. The results show that the variation of the thickness of vanadium oxide films can significantly change their optical performance.
