Povzetek

V okviru diplomskega dela smo izdelali protirefleksijske prevleke iz Al2O3 po metodi sol-gel. Za primerjavo smo naredili še prevleko SiO2 po enakem postopku. Prevleke smo nanesli s postopkom potapljanja in jih toplotno obdelali s sušenjem pri različnih temperaturah oziroma s kuhanjem v vreli deionizirani vodi. Protirefleksijske prevleke smo nato analizirali z vrstičnim elektronskim mikroskopom (SEM) in določili optične lastnosti (odbojnost, motnost). Ugotovili smo, da so vse prevleke iz Al2O3 in SiO2 izdelane kakovostno, brez razpok, te smo na posameznih mestih opazili le pri prevleki iz Al2O3, ki je bila sušena pri 200 °C. Vzrok za njihov nastanek so bili prašni delci na steklu. Prepustnost svetlobe skozi steklo s prevlekami je bila v vseh primerih malenkost boljša kot pri steklu brez prevlek. Najboljše antirefleksijske lastnosti je imelo steklo s prevleko iz SiO2, ki je imelo tudi najnižjo motnost.

Sekundarni naslov: sol-gel production of Al2O3 anti-reflection coatings
Sekundarni povzetek: In the frame of diploma thesis Al2O3 antireflective coatings using the sol-gel method were fabricated. However, for the comparison also SiO2 coatings were made . Coatings were applied by dip-coating technique and thermally treated through drying at different temperatures and boiled in deionized water. Anti-reflection coatings were analyzed with scanning electron microscope (SEM). Also their optical properties (reflection, haze) were studied. It was found that all the Al2O3 and SiO2 coatings were of good quality and free of cracks, except the Al2O3 coating dried at 200 °C which showed some cracks. The reason for their occurrence were dust particles on the glass. The light transmission through the glass with coatings was slightly better than the one that was not coated. The best anti-reflection properties were observed in the case of SiO2, coating which also had the lowest haze.
