In this work we present the results of investigations relating to certain optical properties of thin films of Al2O3 (aluminium oxide) deposited on substrates made of quartz glass, using the sol-gel method. In our opinion, promising results came out photoluminescence and transmission of these layers, whereas the study conducted for the use of these materials in optoelectronic applications. Photoluminescence...
Here we present the results of the measurements of photoluminescence properties of thin films of MgO (magnesium oxide) on Si substrate (mono-crystalline (111) silicon). The samples were prepared by the sol-gel method that is very simple method for fabrication metal oxide layers on different kind of substrates. We carried out the photoluminescence experiments at a wide range of temperatures from 10...
In this paper photoluminescence (PL) properties of ZnO (zinc oxide) thin films on Si substrates are presented. Samples were prepared by sol-gel method. Photoluminescence experiments where carried out at different temperatures (10 K- 300 K). Registered spectra exhibit multiband structure witch depends on the temperature and preparation conditions.
