The optical properties of the HQ Langmuir-Blodgett films (Y-type) have been studied in the range of ultraviolet-visible light (λ=2755—8266nm) by using the spectroscopic ellipsometer. The high absorption of the LB films in different frequency ranges have been discussed. We have also carried out the theoretical computation and numerical value fitting by using the Lorentz oscillator model for the films and the fitting results were in agreement with the experiment data.
