SnO2 composite film incorporated with different mass fraction of La2O3 was developed as a sensitive reagent;the optical properties of the thin films exposed to various volatile organic compounds saturated steam were studied by VIS spectra.3.0%La2O3(mass fraction)SnO2 thin film is more special
and the composite film is chosen as sensitive reagent and fixed on the surface of optical waveguide
to develop a kind of optical waveguide gas-sensing element.This element responses significantly to 4×10-6(volume fraction)of chlorobenzene vapor.
