Rare-earth elements are effective for engineering the optical properties of materials for a range of applications from lasers to quantum information technologies. Here, the authors investigate the temperature-dependent properties of Er3+ photoluminescence in Er2O3 thin films, focusing on the Stark-Stark transitions and how their temperature-dependent behaviour results from electron-phonon interactions.
