Abstract

Silica-tin dioxide thin films doped with Er³⁺ ions were fabricated and investigated. Different parameters such as heat-treatment temperatures, molar concentrations of SnO₂ as well as Er³⁺ ions concentration were changed in order to obtain the best properties of presented thin films. Using several techniques, thin films were characterized and proved to be crack-free, water-free and smooth after a heat-treatment at 1200 °C. Aiming to application in optics, the transparency of thin films was also evidenced by transmission spectra. Based on the photoluminescence measurements, the mechanism of energy transfer from SnO₂ nanocrystals to Er³⁺ ions was examined and discussed.
