What is it about?
This research explores how rare earth elements—like europium, cerium, and erbium—can be added to gallium oxide (Ga₂O₃) to greatly improve its ability to emit light and detect radiation. The review summarizes recent progress in making these materials using different synthesis methods. It shows how they can be used in next-generation devices, like UV sensors, LED lights, and radiation detectors.

Why is it important?
Gallium oxide is a promising material for next-generation electronics and optical devices. By doping it with rare earth elements, scientists can unlock new functionalities like brighter luminescence and faster radiation detection. This helps improve technologies in healthcare, environmental monitoring, and advanced communication systems.
Perspectives
This study opens new pathways for tailoring the optical and electronic properties of gallium oxide using rare earth elements. Future work will explore how to fine-tune dopant concentrations, improve crystal quality, and develop scalable fabrication techniques. These advances could lead to more efficient UV photodetectors, radiation sensors, light-emitting devices, and even biomedical tools, expanding the role of Ga₂O₃ in future high-tech systems.
