| Abstract: | The gas sensing optical characteristic of rare-earth element (La, Gd, Dy) doped films is studied. The transmission spectra of different films in alcohol, acetone, andammonia gases are recorded. Considering the electronic cloud distribution of the material, the gas sensing mechanism is discussed. |
