Abstract
The properties of Er3+-doped gallium lanthanum sulphide (Ga-La-S) thin films prepared on a silicon substrate by femtosecond pulsed laser deposition (fs-PLD) were studied as a function of process temperature. The films were characterised using Transition Electron Microscopy (TEM) imaging, X-ray Diffractometry, Raman spectroscopy, Fluorescence spectroscopy (FS), and UV-Vis-NIR spectroscopy. The results show that by increasing the substrate temperature the deposited layer thickness increases, and crystallinity of the films changes. The room temperature photoluminescence and lifetimes of the 4I13 / 2→4I15 / 2 transition of Er3+ are reported in the paper.
