Maqola haqida umumiy ma'lumotlar
Optical properties of thin films and nanomaterials, including absorption, transmittance and reflection in the visible and infrared regions of the radiation are of great importance. Materials such as ZnS and MgF2 are common optical materials that can be used as coatings and thin films. In this paper, some samples of coatings and thin films such as ZnS, MgF2, and Au / MgF2 on a glass substrate were spectrally simulated in the range of 200 to 1100 nm. The transmission, reflection, and absorption spectra were studied for the simulated samples using Filmetrics and Macleod softwares. The samples were simulated for thicknesses of 10 up to 100 nm. After that, some of the corresponding real samples were made and examined with the absorption and reflection devices; the results of which have been compared with the simulated ones. The spectral analysis, reflective spectroscopy and colorimetry were also included. Furthermore, characterization of each sample were performed by Raman spectroscopy. In summary, ZnS showed 60% transmission in the visible and near-infrared regions for thicknesses of 10 to 100 nm in the simulation, and for the two real samples made at 28 and 40 nm thicknesses. The MgF2 coating showed a reflectance of 4 to 8% for thicknesses of 10 to 150 nm in the simulations, respectively. In practice, MgF2 coating showed a transparency of between 95 and 99%. Coating of 135 nm of MgF2 on 7 nm of gold is found to be able to increase the transparency from 35% to 45% in the infrared region.
