Photometric Measurements

In this paper, we describe a method of fabrication of metal–dielectric mixtures (cermets) deposited by vacuum evaporation. Our study is mainly concerned with co-evaporated mixtures of copper and lead iodide. The stabilization of the evaporation rate of copper and lead iodide enables us to obtain a homogeneous mixture of these twø materials whose mass concentration C is determined from a previous calibration. Photometric measurements carried out on these films lead to the determination of the optical constants N (the index of refraction) and K (the coefficient of absorption). We present here the results obtained for mixtures of low concentration in copper. These results are compared with those obtained from the Maxwell–Garnett theory.
